metacity forgets "(on Hostname)" annotantion on remote apps sometimes

Binary package hint: metacity

Hi! This report is about the latest Metacity on Feisty.

Metacity usually tries to add an "(on Hostname)" annotation to applications that run on remote hosts but use the local machine's X server. For instance, I run Amarok on another computer using "ssh -fnX Hostname.local amarok", and the hostname is normally displayed in the window's titlebar.

I'm not sure what causes the problem, but often the annotation disappears. In Amarok's case, it always disappears if I reduce it to a Notification Area icon. When I restore the window, it looks just like a local window. When Amarok changes its title (for example, when the track changes) the annotation returns. It doesn't disappear if I minimize it, just if I iconize it.

I'm almost sure I've seen this for other applications, too, but this is the one I can consistently reproduce the bug with.
