[KPhotoAlbum] kphotoalbum crashes at start

[Henk van Capelle]

All,


Maybe this is of interest.

I have a working Kphotoalbum 4.7.2 using Dominiks ppa on Linux Mint 18, Cinnamon.

I remember that when I first installed it I also had the crash on startup problem. I subsequently uninstalled it and re-installed 4.7 from the regular Mint repository. Some days ago I tried the ppa again and this time it worked.

If I can help with any other information let me know.

Hi Dominik,

I'm taking you in to this thread because I think there might be a packaging
bug.

Short(ish) summary of the situation:

Rupert Mohr uses the kphotoalbum 4.7.2 from your xenial ppa.
On his system, kphotoalbum crashes at startup.
Looking at the output of ldd, his kphotoalbum binary links to both Qt4 and Qt5
libraries.

The Qt5 libraries seems to be transitively linked via either of these:
libkipi.so.11
libkface.so.3
libkgeomap.so.2

Looking at the build log[1], there is indeed a kf5 package (libkf5kipi-data)
mentioned.

Is it possible, that this is the cause for the linker problem?

Cheers,
  Johannes
