Build 11/16/2012 random crashes on Mint 13

Hi, I'm using Linux Mint 13 (Maya) and I've just updated to SoulseekQt Build 11/16/2012. Many crashes happen randomly when selecting the "expand folders" and the clear "completed and aborted" options in the uploads menu. It happens randomly, crashing the client instantly and with no error messages. I have to restart the client to keep the downloads and the uploads running again. Is this a known bug or something I have to work around with? Many thanks.

Hi Nir, sorry for the late
Hi Nir, sorry for the late reply. I've been busy with stuff and I had my time figuring out how to debug in Linux. So it crashed again (even with the last build 11/22/2012), and I managed to have a crash report. I will copy-paste here everything from the "run" command towards the end.

Thank you Nir and keep up with your awesome work.
Hi woolworm,
Hi woolworm,
I think I got the same bug on Windows when I was using the 4.8.* Qt libraries. The crash does not occur with 4.7.*, which is what SoulseekQt is originally compiled against. Can you check the version of the Qt libraries on your Linux machine?
Hi Nir,
Hi Nir,
I checked on my synaptics package administration panel, and it seems I have this exact version of the Qt libraries installed: 4:4.8.1-0ubuntu4.3.
Yeah, that's 4.8.1 there.
Yeah, that's 4.8.1 there. That's a bug in the library, and I haven't found a way to get around it. If you have the option of downgrading to 4.7.4, I'd recommend that as it's generally more stable than the 4.8.* variety.
It seems that the 4.7.4 is
It seems that the 4.7.4 is the version used in the Mint 12 (Lisa) distro, and since I have the version 13 (Maya) it happened that the Qt libraries have upgraded to 4.8.1 (I actually read that in the actual Mint version 14 (Nadia) it's automatically upgraded to 4.8.3 as seen here http://distrowatch.com/table.php?distribution=mint). So it seems not a real bug, just a normal process of library upgrades that comes with the Mint distros.
So I searched a bit around the web looking for a legit 4.7.4 package, but it appears there's no way to get it. I tried to look in the Qt releases page, but there's no sign of the 4.7.4 (http://releases.qt-project.org/qt4/source/).
What do you recommend? There's a Soulseek build I can use at the moment that has a compatible library with the one I'm using?
Are you using a 32-bit or 64
Are you using a 32-bit or 64-bit version of Linux? I can try statically linking Qt to the SoulseekQt executable.
I am using a 64-bit version
I am using a 64-bit version of Linux.
Try this one:
Try this one:
http://www.slsknet.org/SoulseekQt/Linux/SoulseekQt-11-22-2012-64bit-stat...
Unfortunately, it appears I'm not allowed to distribute SoulseekQt with Qt statically linked without a commercial license, so I'm not going to be able to provide those on a regular basis...
Thank you Nir, I will use it
Thank you Nir, I will use it and keep you updated about the crashes. But I have a few questions: what is really changed in this version you gave me? Does it mean that Soulseek Qt will not work properly in the most recent versions of Linux Mint?
Thank you again.
The executable I linked you
The executable I linked you to actually contains a copy of the 4.7.4 Qt libraries to be used instead of whatever Qt libraries you happen to have on your system. That's why it's considerably bigger. According to the Qt license, I'm not allowed to distribute statically-linked versions of my program without a commercial license, which I don't have.
I see. I hope that the
I see. I hope that the developing of Soulseek Qt for Linux will not be put aside because of these libraries issues.
Anyway, thanks for your help Nir, you are an awesome dude.
Thank you woolworm! I have no
Thank you woolworm! I have no plans of giving up on SoulseekQt for Linux, it's just that it'll have to use whatever Qt libraries happen to be on the machine, compatibility problems and all. Hopefully the particular bug you reported will be fixed in a future version of 4.8.*.
Turns out it was something I
Turns out it was something I was doing after all. It has to do with the way the progress bar on the user line is removed when expanding a user who only has one download folder from them. I delete the progress bar object but do not officially remove it from the user line. For some reason this works fine with Qt 4.7.4 but not 4.8.*. This should hopefully let you use SoulseekQt with your existing libraries, and will apply to all future releases:

Thanks, Nir
