           Summary: crash after playing with tags (seems to be rather a
                    crash in Qt or kdelibs)
           Product: digikam
           Version: 0.10.0-beta1
          Platform: unspecified
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: Regnaron web de


Version:           0.10.0-beta1 (using 4.1.00 (KDE 4.1.0), Gentoo)
Compiler:          i686-pc-linux-gnu-gcc
OS:                Linux (i686) release 2.6.25-gentoo-r7

I opened digikam, created a new tag, tagged some images with that tag, deleted some tags from some of the images and finally closed digikam. When I closed it, it crashed with the backtrace below. So far I have not been able to reproduce this crash. Also: Digikam does not really seem to be the culprit anyway... Looks to me more like a problem in kdelibs or Qt?

Application: digiKam (digikam), signal SIGABRT
