Gecko crash in Thunderbird/F8

[Mickey Bankhead]

I've recently installed F8 on my new Dell, and I've got a terrible 
annoying problem with Thunderbird...

If I launch Thunderbird, it opens fine. Every time I click to open and 
read any e-mail message, I get this pop-up Gecko Crashed window, and 
Thunderbird crashed back to the X Desktop. 
I can fix the problem by yum erase thunderbird, then yum install 
thunderbird.  It works for ONE time I load thunderbird.  As soon as I 
close Thunderbird, the problem starts over, and I cannot click to 
open/read any e-mail message again until I yum erase thunderbird, and 
yum install thunderbird.....!
I've tried:
1. checked all the log files in /var/log, but no errors post when 
thunderbird crashes
2. I've Deleted the files in the /tmp folder - no effect
3. I've checked google, and this list and thunderbird's support page - 
no help...
4. Interestingly enough, I can send mail, forward mail, reply to 
messages without any errors, and after a fresh re-install of 
Thunderbird, I can open and read mail without error, but ONLY until I 
close thunderbird once.  After that, on the 2nd time I open thunderbird 
and every time after that, simply clicking to open a message causes 
thunderbird to crash with a gecko crash and thunderbird crashes back to 
the blank desktop....

My config:
New Dell Optiplex 755 with dual core intel 6750s, 2GB 800mhz. ATI X1650 
dual-dvi card with dual monitors,
Running F8 x586 with all the current patches as of 12-20-07, and 
Thunderbird 2.0.0.9
