Description of problem:
After running yum update (Sep 08), no gnome-session is stable: each time I login, the session is immediateliy killed ("Oh, no. Something has gone wrong").
I could get rid from this behaviour by downgrading (the updated) glib2-2.29.90-1 to version glib2-2.29.18-1.fc16
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.yum update: installs 2-2.29.90-1
Each gnome-session fails immediately
The session continues
There's a reason why the glib-2.29.90-1 build is in an update together with a newer gnome-shell...
