Bug 314248

Application: digikam (2.8.0)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.5.0-21-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed: after tagging ca. 40 new photos with a new tag, I exported them to html using one of the templates ("floating frames" as far as I remember) as I have done 10 times before. But this time Digikam crashed -  ???

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
