Comment 1 Rex Dieter 2009-05-27 11:32:46 EDT
Is this reproducible with kde-4.2.3 (in updates)?
Comment 2 Ian 2009-05-27 11:56:58 EDT
% rpm -q kdelibs

Still crashes as before.
Comment 3 Steven M. Parrish 2009-05-30 22:50:37 EDT
Thank you for the report.  This is an issue that needs to be addressed by the
upstream developers.  Please report this upstream at http://bugs.kde.org  and
add the upstream information to this report.
Comment 4 Ian 2009-06-01 11:19:37 EDT
OK, I think this is the bug:


and this is fix:


I assume this will be in KDE 4.2.4, scheduled for this week :)

Sorry, I should have found this on KDE first.
Comment 5 Rex Dieter 2009-06-01 11:30:49 EDT
np, looks like qt-4.5.1 mitigates this issue as well.

We'll pick up the fix when 4.2.4, sure (working on it).
Comment 6 Kevin Kofler 2009-06-01 11:38:46 EDT
Unfortunately that commit only went into 4.3 trunk, not the 4.2 branch.

(Grrr, yet another bugfix which didn't get backported. The KDE project needs to have a stronger policy about bugfixes having to be backported.)
Comment 7 Steven M. Parrish 2009-06-28 20:43:40 EDT
Do we want to backport this ourselves or just wait for 4.3?

Comment 8 Rex Dieter 2009-06-28 20:50:22 EDT
At this point, I'm inclined to wait for 4.3
