Sorry about the silence; I've recently upgraded to Fedora
Core 3, and haven't seen any crashes or weird behaviour yet
(*knocks wood*). I'll keep an eye on things, and will get
back to you if I manage to reproduce the problems and upgrade
my gdb skills to produce what you requested above.
Sounds to me like you had a kernel problem. Hopefully now you'll be able to
finish the VC stuff at some point ...
