(In reply to comment #1) > I also have this crash > (snip) > And Plasma-desktop does not restart after this crash. Here it does. But DrKonqi gets activated only for the first crash Created attachment 80727 [details]

plasma-desktop (4.10.80) on KDE Platform 4.10.80 using Qt 4.8.4
Seem to happen when clicking on a grouped task, as the OP said.

I have several pdf files open in Okular of which some are minimised. Clicking on the Task Manager to select a specific pdf caused Plasma to crash. Reproducible only sometimes, happened twice today.

- What I was doing when the application crashed:
Click on a grouped task in the plasma taskmanager bar.

*** Bug 321822 has been marked as a duplicate of this bug. *** *** Bug 321918 has been marked as a duplicate of this bug. *** I can always reproduce the issue: 1. Press Alt-Tab to change to another task 2. Click a group of tasks The crash only happens when following these steps. If you don't press Alt-Tab, it doesn't happen. I ran AddressSanitizer on this crash, and it seems to be a use-after-free on a TaskGroup object. But I'm not sure how to fix it. Git commit 9bba9fcd5fb34316eb0787f3c51dc95b6c7d1404 by Eike Hein. Committed on 10/07/2013 at 11:27. Pushed by hein into branch 'KDE/4.11'. Don't keep a stale model index around.

Tagging and release is today according to http://techbase.kde.org/Schedules/KDE4/4.11_Release_Schedule kde-workspace.git only shows v4.10.80 and v4.10.90 tags right now, which should be beta1 and beta2, respectively, so as far as I can see the fix should be making RC1 indeed. *** Bug 322202 has been marked as a duplicate of this bug. *** |
