Indeed it doesn't seem very likely does it!

I tested it on another SL3 machine and got the same results (crashing in 
the same place), on that I have:

$ rpm -q tzdata glibc seamonkey seamonkey-nss thunderbird
tzdata-2006m-3.el3
glibc-2.3.2-95.44
seamonkey-1.0.8-0.2.SL3
seamonkey-nss-1.0.8-0.2.SL3
thunderbird-1.5.0.10-0.1.SL3

which I believe are current for SL3.0.8 though I suppose I might have 
missed something.  On the SL4 system we have:

$ rpm -q tzdata glibc seamonkey seamonkey-nss thunderbird
tzdata-2006m-3.el4
glibc-2.3.4-2.25
seamonkey-1.0.8-0.2.el4
seamonkey-nss-1.0.8-0.2.el4
thunderbird-1.5.0.10-0.1.el4

btw both the SL3 and SL4 machines are i386 arch since I forgot to say 
before.

Yup we have the new seamonkey{-nss,} etc, setting LD_ASSUME_KERNEL also 
makes no difference so it seems unlikely to be an issue with the nptl 
libraries.
