Unless there's a race condition in the library somewhere ... but then it still wouldn't crash on translating a QPoint.
Thank you for the patch, but I really still have to find a way to reproduce this bug before just applying this blindly - it might be treating a symptom instead of addressing the root cause.</pre>

Note that we didn't even get any reports through any of the pre-releases about this, AFAIR.
I'm typing this from a cellphone right now, but I hope when I get home tonight I'll finally get around to setting up a 32 bit VM, and I'm hoping it'll crash there so I can throw all the gdb/valgrind/asan at it we got :).</pre>

Simple steps to reproduce this crash.
1) Pin any task/application to taskbar using "show launcher when not running" option.
2) Close application.
3) Desktop crashes.
Reason :
1) In Tasks::itemGeometryChanged(int,int,int,int,int) line 300 it checks for three conditions,
-> pointer to task is not null
-> taskItem itself is not null
-> scene is not null
2) This condition gets false when item is LauncherItem. In function later line 334 when calling iconRect.moveTopLeft(QPoint) function it gets crashed.
Patch :
This patch adds check in if condition to check if taskItem is TaskManager::LauncherItemType and return from function if this is launcher item.</pre>
