[Monotone-devel] error in mtn merge hook

[Faré]

I have the below problem when I try to merge one of my branches with
monotone 0.37 (base revision: c21eefc002b8f9c430e9f4cc16c4af7b852f54ec)
on debian i386. Can you suggest a way to be able to merge and update?

It looks like a bug in monotone's standard lua hooks for merging.
