Package: gnome-terminal
Version: 2.14.2-0ubuntu1
Severity: normal

There is a particular combination of menu commands that causes gnome-terminal
to block X input until it is killed. It may be sometimes necessary to do
a full reboot to regain control of the system.

The symptoms are:
1. Mouse pointer moves as usual, but no clicks are registered.
2. Background windows are still repainted (in my case: gnome-panel).
3. You need to kill gnome-terminal or X to regain control.

Steps to replicate the error:
1. Make a new terminal profile that takes a while to open
(Using Edit>>Profiles and New button.) Call it 'Blocker'.
You can use ssh to server that silently drops SYN packets.
2. Use File>>Open Tab>>Blocker once.
3. While the tab is opened but empty, open File>>Open Tab directing
mouse pointer to Blocker entry, but NOT clicking it.
3. When the Blocker tab closes (because trying to connect to server
failed), the menu will stop to be repainted and gnome-terminal will
block X input.

I occasionally have similar problem with the gnome-panel that stops
receiving input and at the same time it somehow prevents from switching
windows and workspaces so I'm stuck with the input to just a single
application window. This looks like it may be also metacity problem or
related to some under-the-hood shared Gnome component which blocks
indefinitely (and shouldn't).
