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

[Rainer Dorsch]

Sorry, I misunderstood.

The second crash is worse:
- The upstream developer think it is Debian or QT related and there is no 
known workaround
- And it is still there with 100% occurrence probability:

rd at h370:~/tmp.nobackup$ digikam 
digikam.facedb: Cannot found faces engine model "shapepredictor.dat"

[1]+  Stopped                 digikam 
rd at h370:~/tmp.nobackup$ 


It is not clear to me though if it has something to do with the faces 
features. What I just realize when looking at the failing assertion, it seems 
to be the same assertion in qlist which triggers the abortion. Could be by 
coincidence though.
