Bug#784123: vinagre: Grabs mouse and doesn't want to release it

[Mike Neilly]

Package: vinagre
Version: 3.14.1-1
Followup-For: Bug #784123

Dear Maintainer,

This still exists in Debian 8.6 as shown in the following video:

https://youtu.be/_Gf5XQkSd8Y

This video shows a full screen VNC session using vinagre on Debian
8.6. "At some point" mouse control is lost. Clicking icons in the
remote windows VNC session no longer works. Clicking on the terminal
on the left brings up the Linux terminal used to launch
vinagre. Leaving full screen with F11 reveals the Linux context menu
is selected on the desktop behind the VNC session and mouse control is
lost on the Gnome desktop until hitting Alt-Tab.

It seems non-deterministic as to just how the situation occurs. Using
Super-PageUp and Super-PageDown, Alt-Tab and switching in and out of
full screen with F11 are probably the best way to reproduce
this. Sometimes it seems stable for a while then things stop working.

There are also error messages reported by both vinagre and gnome-shell
at the time of failure:

Vinagre reports:

mneilly at spiderbyte2:~$ vinagre
(vinagre:13166): GLib-CRITICAL **: Source ID 630 was not found when attempting to remove it

While gnome-shell reports:

mneilly at spiderbyte2:~$ gnome-shell --replace
current session already has an ibus-daemon.
