Hey Ryan,

Thanks for your reply. Actually, after posting my message I found a similar 
report from way back in 2005 (I think). I should have searched that before but 
the fact a user reported an actual crash with a similar backtrace at the same 
point made me a bit confused. As it may be - thanks again. :)

Regards,
Christian
