Version: 3.3.2 (using KDE 3.5.2, Kubuntu Package 4:3.5.2-0ubuntu18.1 dapper) Compiler: Target: i486-linux-gnu OS: Linux (i686) release 2.6.15-27-386 In the other similar bug reports I did not see any backtrace similar to this one, so I'm going to report this. Reproducible by starting KDevelop. Looking at the backtrace it seems it's a memory corruption bug, most likely a processEvents() bug looking at the KIO async stuff.

I had svn version control. I disabled it and it seems the crash has gone.
