I've tested this on one sl5 box with a download of the firefox 3.6.4 
binary from firefox.com and get similar behaviour except it exits with 
code 1 rather than generating a segv...

Again removing the extensions.ini is enough to make it run, so I think I 
can rule out the srpm/packaging as the main badness here.

which seems to just leave:

   something fairly odd in our setup

   bug in firefox 3.6.4

   really weird bug in the extension

as plausable causes.

I'd still like to know if it affects 3.6.4 on any other machines!

Anyway time to finish the evil hacks to our firefox wrapper and then try 
to get some sleep :-(
