[Digikam-devel] Crash while deleting tag in ImageDescEditTab

[Johannes Wienke]

Hi Marcel,

I just noticed that digikam crashes if you delete an album in the
imagedescedit tab. Backtrace is:

Thread 1 (Thread 0x7faf753337c0 (LWP 7271)):

event=0x7fff8ea70440) at
/home/languitar/workspace/digiKam/digikam/albumtreeview.cpp:716

The reason for this is that the tag is already deleted by the
TagModificationHelper so the pointer in the dynamic cast points to
invalid memory.

Does using AlbumPointer in for the whole context menu handling help to
resolve this?
