gtk warnings when using via X11 forwarding

[Alexander Sashnov]

Ubuntu 14.04 x64 up-to-date on 3 Sep 2015
geany 1.23.1 (built on May 19 2013 with GTK 2.24.18, GLib 2.37.0)

alex@umbrella:~$ geany t.txt

   Press ENTER several times in Geany window: nothing appears in terminal - it's OK

Now run Geany via ssh on current machine and do the same thing with pressing ENTER in Geany window:

  $ ssh -X another_user@localhost

This time GTK warning appears on every ENTER press:

 (geany:7194): Gtk-WARNING **: Failed to parse menu bar accelerator 'disabled'
