unity/compiz locks up when modifying the partition layout

[Glenn Washburn]

When using parted or gparted, the desktop will become unresponsive after successfully modifying the partition layout. The mouse is movable, but clicking or using the keyboard has no effect. Sometime after a long while responsiveness will return, but sometimes it appears not to and compiz must be killed.

Unity does output these warnings:
WARN 2013-02-27 23:29:18 unity.libgdu <unknown>:0 Partition /org/freedesktop/UDisks/devices/sdb11 is a logical partition but no extended partition exists
WARN 2013-02-27 23:29:18 unity.libgdu <unknown>:0 Partition /org/freedesktop/UDisks/devices/sdb8 is a logical partition but no extended partition exists
WARN 2013-02-27 23:29:18 unity.libgdu <unknown>:0 Partition /org/freedesktop/UDisks/devices/sdb6 is a logical partition but no extended partition exists
WARN 2013-02-27 23:29:18 unity.libgdu <unknown>:0 Partition /org/freedesktop/UDisks/devices/sdb5 is a logical partition but no extended partition exists
WARN 2013-02-27 23:29:18 unity.libgdu <unknown>:0 Partition /org/freedesktop/UDisks/devices/sdb10 is a logical partition but no extended partition exists

I'm on Precise, with unity version 5.14 and compiz version 0.9.7.8-0ubuntu1.4

I take that back unity is still locking up, though it seems less often. I've attached the xsession-errors file.
