compiz crashed with SIGSEGV in g_variant_type_info_get_type_string()

[Ranadip]

The crash occurred when I placed my laptop on the dock. The dock is connected to a LCD monitor. It seems compiz crashed while trying to set the displays on the laptop and the external monitor.

This definitely should be fixed in Oneiric, please re-open if this is not the case.
