Maybe, maybe not.  In gnome-vfs-2.5.5, they switched to using the new
XDG shared-mime-info stuff for getting MIME types.  This may have some
issues as it hasn't been as fully shaken out as g-m-i.  I still need to
do an audit of this port.

Can you run nautilus in gdb, then get a stack trace?

Then this is most likely a memory bug.  Since I can reproduce it with
malloc debugging turned off (and I'm on Nautilus 2.5.4), I bet this
problem is pretty insidious.  I'll see if I can get more debugging info.
