crash without any error

Hi, i'm from brazil so sorry for my english.

I use the last MAC build (SoulseekQt-2014-1-15) and the client crashes at some differents actions like: searching something, changing tabs, deleting any file form transfer list, and some more situations. First i can report a crash log here, but i don't know where is it. And second, i guess that there isn't any crash log because it simply shows that "wait sign" of OSX mouse pointer and then you have to press CTRL+OPTION+ESC to wait to force quit the client. I recently have formatted the OSX, but i guess this problem started when i updated to Mavericks 10.9.1.

Any suggestions?

Thank you,

André
