I've seen this before. But like you I wasn't able to reproduce. Nevertheless, I'm marking it as confirmed/assigned. SVN commit 991531 by aseigo: don't hang onto a kconfiggroup pointer. it's cheap enough to make them when needed and then when the config file is deleted, bad things don't happen BUG:198537 M +19 -15 Global.cpp M +1 -2 Global_p.h WebSVN link: http://websvn.kde.org/?view=rev&revision=991531 SVN commit 991533 by aseigo: backport of fix to 198537 BUG:198537 M +18 -14 Global.cpp M +1 -2 Global_p.h WebSVN link: http://websvn.kde.org/?view=rev&revision=991533 |
Application that crashed: lancelot Version of the application: 1.7 KDE Version: 4.2.95 (KDE 4.2.95 (KDE 4.3 RC1)) "release 139" Qt Version: 4.5.2 Operating System: Linux 2.6.27.23-0.1-default x86_64 Distribution: "openSUSE 11.1 (x86_64)" What I was doing when the application crashed: Note: I do not know if what I did before the crash is important, since it seems a bit far-fetched but anyway: all I did was to change the plasma theme from air to glassified. The theme changed as it should, but lancelot crashed as well. It restarted itself as it should though. I've tried to reproduce it but so far has been unable to do so. If the theme-switch indeed caused lancelot to crash it seems to be a rare occurence. -- Backtrace: Application: Lancelot (lancelot), signal: Segmentation fault [KCrash Handler] #5 0x0000000000b9e7f1 in ??
