Beat Wolf: Is there a Qt tracker bug number to follow this crash? 
We also experiment it in some KDE-Edu programs and I saw this backtrace related to some Amarok crashes so it looks like a Qt problem widely spread.

*** This bug has been marked as a duplicate of bug 210158 ***

i could not find a reference to a upstream bugreport, just aaron closing a dupe of this bug with the argument that it's a upstream bug and that it should be submitted there

I knew it was familiar, look at the reporter of the dupe!

I am not sure what should be done in that case and I don't know how to report KDE crashes in Qt bug tracker.
What I know is that I get Qt related crashes all over the place since we switched to 4.6 and it's not improving. Not sure either how kde-qt is synched with 4.6 master, I was told it's lagging (so why are we using it? what will distros use for the beta 1?)

in that case upstream reports have to be opened

http://bugreports.qt.nokia.com/browse/QTBUG-5090

bug 210158 is not a duplicate of this bug, the backtrace is different.

*** This bug has been marked as a duplicate of bug 214719 ***

after upgrading qt to 4c7fac3570679a0871f8aefd104bcb65ca13614b, this crash does not anymore appear.
