1. Install FC6 (or at least the FC6 metacity)
2. Do a "yum -y update --enablerepo=development compiz"
3. The new compiz is installed
4. Try to switch to using compiz:
gtk-window-decorator will crash
The problem is that compiz uses a library private to metacity, and its interface
must have changed between FC6 and F7, thus making gtk-window-decorator crash in
compiz should hard-code its dependency on metacity (and its private library) to
avoid such problems.
Installing metacity from F7 as well makes it work fine.
Ah, ok, I added
Requires: metacity >= 2.18
to the spec file.
