Description mohamed malik 2011-08-03 08:15:27 UTC

Version:           2.0.0 (using KDE 4.7.0) 
OS:                Linux

digiKam crashes while trying to tag faces. When many like faces are selected and when trying to tag the name of the faces digikam crashes everytime. However if one like face is selected at a time it doesn't crash.

For an example if 15 faces of the same person is selected and when trying to assign the name tag to the person the application crashes.

This seems to be working well from 2.0 beta 3 - 2.0 RC..!


Reproducible: Always

Steps to Reproduce:
Make sure digiKam doesn't crash when trying to tag like faces all at once.

Actual Results:  
Make sure digiKam doesn't crash when trying to tag like faces all at once.

Expected Results:  
Make sure digiKam doesn't crash when trying to tag like faces all at once.
