Comment 1 Dario Andres 2010-02-10 13:00:06 UTC

- Have you tried to simulate the High load situation to check if Plasma crashed again repeating the steps ?
Thanks

Comment 2 anton 2010-02-11 11:10:36 UTC

I was not able to reproduce this; I also remeber the time it happened the system was just after awaking from suspend to disk, but after a number of such awakes the crash still did not happen.

Comment 5 Aaron J. Seigo 2010-05-11 04:46:17 UTC

the backtraces in the two duplicates point to this line in QGraphicsScene on line 2596:

QGraphicsWidget *last = d->tabFocusFirst->d_func()->focusPrev;

it's a tab focus tracking bug in Qt.

Comment 6 Alexis MENARD 2010-05-11 04:58:14 UTC

Please update Qt as well as KDE. I fixed a bug related to that long time ago.

Comment 9 Alexis MENARD 2010-07-30 20:22:59 UTC

Well I can't reproduce both bugs on my machine. I'm running Qt 4.7. Can someone try with 4.7? Also the backtraces are incomplete, the first 5 symbols are missing, would be nice if i can get them somehow. Lot of things are happening in addItem...
