I am getting segmentation fault error!

Hi All,
I installed RT and it seems to be working
fine, but some times, the web browser is getting close
suddenly, mostly when I press logout, the http and rt
log says the following error message.

It looks like sending mail in NotifyAsComment part,
I am trying to find out, if anybody knows or faced
this type of problem, can help me out to solve.

Thnx,
-bala-
