There's no database migration needed going from 0.40 to 0.44.  And if
you did need one, yes, it is supposed to tell you, rather than
crashing like this.

Ok, this looks like a real bug: you are trying to do a checkout in the
root directory of a Windows drive, which should be fine, but may never
have been attempted before.  And you didn't specify a directory to
check out into, so it's trying to form the directory name from the
branch name, and losing the drive letter, which makes the path
normalization logic unhappy.

I do not have a working Windows development environment right now, so
I can't fix this bug.  I don't know whether anyone else reading
monotone-devel has the time and the setup to do it.  [To anyone who
tries: I think the problem is either in the system_path() constructor,
or in workspace::create_workspace().]

However, you should be able to work around the problem by doing your
checkouts somewhere other than the root of a drive.  You may also be
able to work around the problem by specifying a directory for the
checkout on the command line.
