Bug#343336: metacity segfaults if workspace goes away that contains windows

[Johannes Berg]

Package: metacity
Version: 1:2.12.1-1
Severity: normal

When, using the workspace switcher preferences, I reduce the number of
workspaces so that a workspace is removed that still contains windows,
metacity segfaults. By tricks (apparently one cannot switch out of X when
metacity has segfaulted and hangs inside gdb because all keyboard events
go to metacity! don't try!) with chvt(1) I was able to get this segfault
inside gdb:

Window manager warning: Log level 8: meta_workspace_add_window: assertion `window->workspace == NULL' failed

Program received signal SIGSEGV, Segmentation fault.

Even though there are no symbols this hopefully helps.
