Description Richard Rondu 2009-12-08 01:33:24 UTC

Version:            (using KDE 4.3.3)
Compiler:          gcc-4.4.2 
OS:                Linux
Installed from:    Fedora RPMs

In fedora 12, after i logged in in kdm, kde begin to start and a "few" seconds later, kded4 and plasma-desktop processes crash. Krunner is working fine so I can launch several kde apps without any problem but kded4 and plasma-desktop refuse to launch.

Running Qt 4.6 and kde 4.3.3

Laptop: Dell Latitude E6500 (with Intel 4500HD)

Comment 1 Christoph Feck 2009-12-08 03:35:32 UTC

Does downgrading your Qt version to Qt 4.5.x help? KDE 4.3.3 may not support the Qt 4.6.0 release.

Comment 2 Christoph Feck 2009-12-08 03:47:06 UTC

If you want to use Qt 4.6 with KDE 4.3, you would have to backport r1035622 and r1057980 to the KDE 4.3 branch to fix this crash.

KDE developers did not backport, as the KDE 4.3 branch is not supposed to be used together with Qt 4.6.

Comment 3 Richard Rondu 2009-12-08 23:52:41 UTC

indeed, downgrading to Qt 4.5 helps. I'll consider backporting those fixes, thanks for the help. Do I need to mark the bug as resolved or something?

Thank you.
