User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.8.0.4) Gecko/20060614 SeaMonkey/1.0.2
Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.8.0.4) Gecko/20060614 SeaMonkey/1.0.2

I have a self-built version of SeaMonkey/1.0.2 with no patches but with debugging symbols in to allow me to raise these issues I am intermittently having.

I have the coredump core.12232 of this to be able to assist hunting this bug.

Please advise if you want any specific information from the code dump or where I should be looking in it to find the problem.

Just to add, I may not have been editing mails in this case, the core file is over 18 hours old and I could not be sure I was editing emails at the time.  I think I may have just been web browsing at the time.
