[Pkg-kde-extras] Bug#1034310: [digikam] [Bug 466170] Digikam 7.9.0 (and 7.8.0) crashes on startup

[Rainer Dorsch]

Hi Steve,

many thanks for applying the patch. I reenabled the splash screen in digikamrc 
and it seems to crash at the same location again:

rd at h370:~$ apt-cache policy digikam
digikam:
  Installed: 4:7.9.0-2
  Candidate: 4:7.9.0-2
  Version table:

I will create a trace and append it to the upstream bugreport:

https://bugs.kde.org/show_bug.cgi?id=466170

Thanks again
Rainer
