            Bug ID: 295340
          Severity: crash
           Version: 2.6.0
          Priority: NOR
          Assignee: digikam-devel at kde.org
           Summary: Digikam crashed while tagging faces
    Classification: Unclassified
                OS: Linux
          Reporter: fredericg_99 at yahoo.fr
          Hardware: Compiled Sources
            Status: UNCONFIRMED
         Component: Face Management
           Product: digikam

I'm sorry for the evasive bug subject, but I'm not sure about what happened...
I tagged faces, and noticed a first bug : every time I tagged a face, several
progress bar appear on the bottom of the screen : "Process Item/Applying Face
change", "Assigning image tags", and "Writing metadata to file".
I expect them to disappear quickly, but unfortunately, the last one ("Writing
metadata to file") does not (whatever the time I wait for it, the progress is
still 0%)
After 5 taggings, I had 5 "Writing metadata to file" progress bars at 0%.
Then, for an unknown reason (I don't really remember what I did, I think I was
trying to cancel the progress bars), digikam crashed.
I decided to keep this bug report, even if not very precise, since the crash
would give me the opportunity to get the back trace, which would certainly help
the bug relative to the progress bar not disappearing, so here it is! (but
maybe this bug report is about 2 different bugs, and in this case I'm very
sorry for that but I don't know how to differenciate them in the backtrace...)
