[Lazarus] Lazarus crashes on startup with "g_object_unref: assertion 'G_IS_OBJECT (object)' failed"

[Joost van der Sluis]

Hi all,

I received a bug-report that Lazarus does not start on Fedora 22. Yeah, 
that version has not been released yet, so we can fix this problem 
before it actually occurs. ;)

It was originally reported against Lazarus v1.2, but I updated to 1.4rc2 
and the problem is still there.

The bugreport can be found here, with a backtrace attached to it:

Regards,

Joost.
