Created attachment 65522 [details] Proposed patch
Please test/review attached patch.
crash stopped with this patch. thank you very much :)
will this patch make it into upstream git sources? it fixes the crash for me.
The patch is a no-op as far as I can say, so I don't see how it can actually fix anything. The problem seems to be elsewhere.
This looks like another problem due to the qDeleteAll in Qt 4.8 . See comment #9 in bug 284889 .
There's no comment #9 in that bugreport, but I've been told elsewhere meanwhile, so fair enough. Can somebody please commit the patch then?
