This seems to be upstream bug http://bugs.kde.org/show_bug.cgi?id=185736, which has already been fixed in KDE HEAD and 4.2 branch. See http://websvn.kde.org/branches/KDE/4.2/kdebase/workspace/plasma/shells/desktop/panelview.cpp?r1=930724&r2=934863&view=patch for the upstream patch.

[Comment 1 Marios Andreopoulos 2009-03-08 01:12:56 UTC]

I want to confirm this bug. Please when you find some time add the proposed patch to the ebuild.

I work on a laptop, using an external monitor, thus every time I log in KDE finds a different resolution and plasma crashes.

ebuild with added patch line

New ebuild with added patch line. Depends on patch file in files sub-directory.

I just tested your ebuild and works like a charm, thanks!
I didn't know it was so easy to apply a patch.

[Comment 5 Tomáš Chvátal (RETIRED) 2009-03-08 19:37:59 UTC]

Fixed in same revision since there will be -r1 comming in few days with the updates from eclass.

[Comment 6 Willard Dawson 2009-03-13 21:46:14 UTC]

How long will the -r1 version be before we see it pushed out?
