crash in Qt; probably due to the click in the taskbar starting a drag of the button and something going wrong with the drag process. do you have an autohidden panel?
No, I didn't have an autohidden panel. But there was a widget which didn't work properly (Activity Bar) - it didn't paint itself and was eating 100% of one CPU core. But the system was still responsive. The crash happened when I clicked on a task in the taskbar. When Plasma was reloaded, it worked OK afterwards.
BTW, the backtrace mostly matches bug 192000 and its duplicates... can you confirm that ? Thanks
Waiting for feedback. Marking as NEEDSINFO.
I hasn't been able to reproduce the problem since. It is true that it looks similar to bug 192000 - it is probably the same problem. I think it can be closed as a duplicate.
