Excerpt from /var/log/messages showing the crash. The Python program that went down was yum.

Description of problem:
Running Gnome. I usually have two gnome-terminals open, one with some 8 tabs (local) and the other (remote) normally with just one.

On the local one I run a root shell (updating the system via yum, sundry sysadminning like checking if outgoing mail did in fact leave) and a few other local shells (getting git, kernel sources; local work; getting/compiling Stone Soup). On the remote I've an ssh running to a remote system, and a screen(1) there. I usually start xemacs and xpdf from some of the "local work" tabs.

When I leave the machine for longer time (say an hour or so for a meeting or classes) the screensaver kicks in. Sometimes in this situation (longer absences, never short ones) I came back and the gnome-terminals are both gone.

Version-Release number of selected component (if applicable):
gnome-terminal-2.31.91-1.fc15.x86_64
yum-3.2.28-8.fc15.noarch
python-2.7-11.fc15.x86_64

How reproducible:
Seems to happen to yum when left running on its own under screensaver (I usually start it before going away for a while, as its disk activity makes the system nearly unusable when mass getting/updating)
