Daniel,
Thanks for the quick reply, It didn't stop at the break
Will this help ?
Rerun under gdb control, as I'm unable to find where this may occur just
from the tack strace given. __virConfReadFile only calls virConfError
which does not call strerror, put a breakpoint in __virConfReadFile and
__virRaiseError and try to find out what is happening please.
Daniel
