[Thunar-dev] Crash when opening files

[Jannis Pohlmann]

Hi Benny,

I just checked out libexo and thunar from /trunk and played around with
them a little bit. When opening some PDFs I noticed that, (almost)
whenever I opened a file, Thunar is closed. Notice the "almost", which
means that it doesn't happen all the time.

My first guess is that it may depend on whether I set up the mime-type
to be opened with a custom program. But I'm unsure about this and I
can't proof this theory.

See below for a backtrace of the crash.

Anyway, you did a great job once again!

Regards,
Jannis
