Description Jaime Torres 2012-06-22 17:28:49 UTC

I started Detect and recognice faces with Clear uncormirmed results and rescan. Keep on Thumbnails view, with no picture selected.
There is no progress bar, no way to know if it is doing anything, except cpu is busy (but his is another bug).
While it is scanning, I create a tag.
Digikam shows a Dialog probably for each image scanned for faces. In my test, it has been 8 dialogs all asking the same, if I want to apply the changes.
When I press ok in the last one (first to be shown), crash.

Console output:

Object::connect: No such slot Digikam::ContextMenuHelper::slotABCContextMenu() in /g/kdegit/extragear/graphics/digikam/digikam/utils/contextmenuhelper.cpp:578

Related to bug 297558

The crash can be reproduced every time.


Reproducible: Always
