[gthumb-list] gthumb 3.3.2 hang on start

[passtschu freenet de]

Hi.

I've updated to gthumb 3.3.2 on linux mint using the repo of 
http://www.webupd8.org/2014/05/install-gthumb-332-in-ubuntu-gnome-1404.html.

When I start gthumb as normal user the window is shown but it is 
hanging, have to kill it.
Started with sudo it's working without problems.

Tried to start on the terminal but no output is shown.
What can I do to get it working or some usefull output?

Thanks in advance
