nautilus crashed with SIGSEGV in strcpy(), error 6 in libglib-2.0.so.0.3102.0

This is happening reliably for me about 50% of the time when I start nautilus in Precise running in VirtualBox on 11.10 host.
The launcher icon pulsates as normal for a few seconds then nautilus crashes. In dmesg I see
nautilus[31311]: segfault at aaaaaaba ip 00be929e sp bfb75fa0 error 6 in libglib-2.0.so.0.3102.0[b7f000+f3000]

This may be a duplicate of bug#804891 but as I am able to make it fail fairly reliably it may be different so I am reporting it as such so that the stack trace and so on will be captured.
