Comment 1 Rex Dieter 2009-05-27 15:32:46 UTC

Is this reproducible with kde-4.2.3 (in updates)?

Comment 2 Ian 2009-05-27 15:56:58 UTC

% rpm -q kdelibs
kdelibs-4.2.3-2.fc10.i386

Still crashes as before.

Comment 3 Steven M. Parrish 2009-05-31 02:50:37 UTC

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 15:19:37 UTC

OK, I think this is the bug:

https://bugs.kde.org/show_bug.cgi?id=190787

and this is fix:

http://websvn.kde.org/?view=rev&revision=961550

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 15:30:49 UTC

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 15:38:46 UTC

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 2009-06-29 00:43:40 UTC

Do we want to backport this ourselves or just wait for 4.3?

Comment 8 Rex Dieter 2009-06-29 00:50:22 UTC

At this point, I'm inclined to wait for 4.3
