Application: calligraauthor (2.9.7)
KDE Platform Version: 4.14.13
Qt Version: 4.8.6
Operating System: Linux 4.2.0-16-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed:
tried to open calligraauthor for the first time.
tried twice.
realized I was opening it from a screen session I open from a previous X session.
calligraauthor succesfully open from krunner

I guess this is a minor issue, but i think an error message should be presented to the user as to what exactly could not be found instead of just crashing out.

thanks for your awesome work on all KDE software.

The crash can be reproduced every time.
