[CentOS] Frequent Gnome Terminal crashes in CentOS 5.1

Ever since I upgraded all my systems to CentOS 5.1 I have been  
getting reports from users about "all their windows disappearing".  A  
little digging revealed that they meant all gnome-terminal windows.   
Since there is only one gnome-terminal process by default for all  
your open terminal windows and tabs, a crash of that process means  
losing all your terminal windows.  These crashes often (but not  
always) occur over night when the system is otherwise idle.

A quick Google search found a problem on Ubuntu related to VTE (the  
terminal emulator widget used by gnome-terminal) but not much else of  
interest.  Has anyone on this list experienced this?  I find it hard  
to believe I'm the only one.  I never saw this issue while running  
CentOS 4.X on these systems...
