Bug#712104: gnome-terminal: gksu gnome-terminal doesn't start in certain conditions

[Ovidiu Angelescu]

Package: gnome-terminal
Version: 3.8.3-1
Severity: important

Hello,
I have done a dist-upgrade against sid in a virtual machine.
Previous gnome-terminal was 3.4.2-1 and it worked ok.
Now in sid we have 3.8.3 and when launch it from gnome menus as Root Terminal
it starts.
If closing launched gnome-terminal window and trying to restart ... no gnome-
terminal window is started.
If I logout and login again gnome-terminal starts as root using gksu but it's
the same as before logout.
It's not a gksu bug because in LXDE when gksu starts lxterminal all is ok.
Also I have removed gnome-terminal 3.8.3-1 and reinstalling old 3.4.2-1 all was
ok.
If starting gksu gnome-terminal from a regular user terminal the following
error messagge is there when gnome-terminal doesn't start:
(gksu:791): GLib-CRITICAL **: g_str_has_prefix: assertion `str != NULL' failed
Also if launching gksu xterm all is ok.
If launching gksu gnome-terminal from an rgular user xterm console .. same
error message.
(gksu:791): GLib-CRITICAL **: g_str_has_prefix: assertion `str != NULL' failed
