Comment 1 Volker Lanz 2009-12-13 14:11:10 UTC 
Thank you for reporting this crash. Can you reproduce it or was it a one-time incident? Also, if it ever happens again (on purpose or by accident), can you please install debug symbols for your distribution? See

http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

for details.
Comment 2 Volker Lanz 2009-12-13 14:56:50 UTC 
Never mind, I can reproduce it with Qt 4.6:

NT
Comment 4 Volker Lanz 2009-12-13 16:58:02 UTC 
SVN commit 1062035 by vlanz:

Don't delete all the info pane's QWidget children on clear(). KDE SC 4.4's
Oxygen KStyle inserts children into widgets for its transition effects that
would get deleted that way.

Maybe this deserves some discussion some day if Oxygen is entitled to modify
the application's object tree? Anyway, this fix works around it and everyone is
happy for now.

Comment 6 Volker Lanz 2009-12-15 01:01:33 UTC 
Reiner: thank you for your feedback. The crash has in the meantime been fixed in the source code repository. A new release of KDE Partition Manager including the fix will hopefully be available within the next couple of days. As a workaround on KDE SC 4.4 beta until then you can use any other KDE Style (System Settings -> Appearance -> Style) than Oxygen.
