Crash when branching BugsEverywhere

Ok thanks. Shouldn't bzr display a more user friendly message though? Like:

"Branch can not be created because Windows does not support symlinks and 
the branch contains symlinks.
There is a plugin called win32symlinks that emulates this under Windows. 
Please install this plugin and try again."

What is the reason for this? The cygwin shell is much nicer than the DOS 
one. So much so that I can't bring myself to use the DOS prompt and the 
cygwin version is out of date and slow. I think it should work 
regardless of which prompt I use. I can't think of a reason why it 
shouldn't - env variables perhaps. Everything seems to work and this 
problem also exists from DOS prompt. I haven't had any other issues 
using native bzr in cygwin (other than the prompts not working in 
Terminator and gnome-terminal).
