I have uncovered a bug in r665575.

I tried to change my max downloading to 2 (from 1) and my max seeding to 5 (from 2). And ktorrent crashed. I forgot I had enabled the debuging symbols when I compiled it so I just hit close and went to launch it again. The KDE crash handler showed up again. I did a backtrace. Here is the output:

My apologies if this is already fixed, but I figured I would get it in before I can't reproduce it.

I just updated to the latest svn (r665880) and the problem still happens. I will try deleting (actually renaming the folder) the contents in my .kde/share/apps/ktorrent folder and see if it still happens.

OK after doing more digging I found out that a particular torrents data was causing the crash. I think what may have caused a problem is, I originally started up a bunch of torrents and let them allocate, but then I realized I wouldn't have room to do all of them, so I removed a bunch of the preallocated files. All except this one prompted me to reallocate the files when I started them. For whatever reason this one decided not to, and cause a crash. I will just readd the torrent, so this should be taken care of on my end.

I will be saving the contents of the folder I removed for a couple of days, so if you would like them, let me know the best way to get them to you.

It's an uncaught exception, will have it fixed in 5 minutes.

OK, shouldn't happen anymore
