Comment 10 for bug 818857

The same behaviour here.
Just to provide additional debugging information, I have run it with gdb:

$ gdb /usr/bin/gedit
(gdb) run 1.txt
Starting program: /usr/bin/gedit 1.txt
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
