[Monotone-debian] Monotone completely broken in Debian testing (I think)

[Francis Russell]

Monotone broke for me completely today in that I couldn't even run mtn
with no options on my x86_64 Debian testing system. Based on the
backtrace I got from GDB and my APT logs, it looks like the upgrade of
libbotan1.10-0 from 1.10.1-1 to 1.10.2-1 is the culprit:

Once I rebuilt the package, mtn worked fine so I guess Botan made some
incompatible ABI change. Can someone else confirm what I've seen?
Unfortunately, the only other thing that uses botan1.10-0 is softhsm as
I couldn't convince it to do anything that confirmed the issue was with
Botan.

What's the easiest way to get this fixed?
