My issue is the following:
I am able to open comics from the filebrowser (Nautilus) without issues, it is also the default program for CBZ and CBR. So no issue there.
But if I want to open the file from the library plain nothing happens.
Tried it with Loglevel Debug and Error but nothing shows up.

My system is an Archlinux, this info comes up when open the Library:
