Roaming profiles are just problematic, even on native Windows servers.  I 
have seen several roaming profiles implode on WinXP client boxes.  I've 
also seen bad behavior with Win2k client/server setups as well.  Symptoms 
include the client creating new profiles, ignoring existing profiles, or 
dialogs indicating profile corruption.

I'm no Samba or programming expert, but that last line looks like a libc 
segfault.  Sig 11 errors a long time ago used to implicate RAM issues, 
usually due to bad contacts or faulty RAM chips.    This may sound silly 
but try powering down the machine, unseating and reseating all of your 
RAM.  If it continues, try reducing the RAM and see if the issue goes 
away (due to a bad RAM stick).  Just my .02 cents.
