            Bug ID: 322022
           Summary: faces and crash
    Classification: Unclassified
           Product: digikam
           Version: unspecified
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: Tags
          Assignee: digikam-devel at kde.org
          Reporter: jtamate at gmail.com

The fraces scan finished long time ago..
I was seeing the unknown faces list, introducing names to the faces..
In one photo, there were 2 faces. One was detected, the other one not.
I manually added the not detected face, introduced both names (without pressing
confirm).
Then I pressed confirm in both of them quickly (once you confirm a face name,
the photo dissapears from unknown faces list), perhaps when the photo was
changing to the next one in the list..And crash.

I've just noticed: 89 threads....

I could not use drkonki (too much information... perhaps the backtrace of 89
threads).
