            Bug ID: 340093
           Summary: Digikam freezed with 100%CPU when rebuilding
                    thumbnails
           Product: digikam
           Version: 4.2.0
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: Thumbnails
          Assignee: digikam-devel at kde.org
          Reporter: mathieu.clabaut at gmail.com

Digikam initially freezed for unknown reason.
So, I've erased digikam4.db and rebuilt the collection (metadata stored in each
photo), but it hangs again, apparently when trying to rebuild thumbnails.

Reproducible: Always

Steps to Reproduce:
1. Open digikam
2. wait

Actual Results:  
Digikams hangs.

Console output :
