Description

I have seen the intermittent hanging of the GNOME Appearance Manager in OpenIndiana, Hipster (and Solaris 11 Express, S11, and S11.1). Research shows that Ubuntu had the same problem and a fix was made available in Debian.

The Ubuntu bug report can be found at https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/554106
It was determined that the desktop effects integration calls GTK functions outside of the GDK global lock. A deadlock is caused by trying to recursively lock the GDK global lock.

The diff can be found at http://launchpadlibrarian.net/43905478/gnome-control-center_1%3A2.30.0-0ubuntu3_1%3A2.30.0-0ubuntu4.diff.gz

The deadlock fix is currently not implemented in http://hg.opensolaris.cz/oi-jds/file/bb01b5720819/patches/control-center-03-compiz-integration.diff
