compiz crashed with SIGSEGV in DeviceLauncherIcon::UpdateVisibility()

[Scott Morgan]

Binary package hint: unity

This crash happens every time I try to open a SFTP mount with Nautilus (first time the bug reporter showed up though)

Windows decorations and Unity disappear, keyboard locks up for X apps but mouse still responds. I can <ctrl>+<alt>+1 to the console and login there.

Some change in Natty in the past week or two as this functionality was okay before.

This also happens when trying to open a samba share. Happens consistently, every time I try to open the share in nautilus.
