Version:           SVN revision 746549 (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc (GCC) 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2) 
OS:                Linux

KWrite was started from a console within a KDE3 session, but it's running as a user set up for KDE4 (according to the How-to at http://techbase.kde.org/Getting_Started/Build/KDE4 I compiled revision 746549). I didn't change any settings, load additional plugins or remove the ones that are activated per default. When opening a file from the "recent files" list, it crashed with the backtrace below. I couldn't reproduce this at all.
