bug#6513: vc-mtn broken with monotone 0.48 (can't even open files)

Try "Options => Enter Debugger on Error" and reproduce the bug, to get
a backtrace.

Thank you, that is very useful to know.
I wrote vc-mtn.el a long time ago but don't actually use Monotone much
these days and don't have much time to devote to it, so if you could
help us fix it, that would be really appreciated.
