Problem trying to specify a revision number for bzr-externals

[Patrick van der Velde]

Hi All

I'm trying to add an externals reference to my repository. It all
works fine when I don't have a revision specifier but as soon as I add
one I get a bzr internal error. The documentation for externals states
that revision specifiers are legal. Any ideas on what is wrong? My
command line is:

bzr externals-add 'D:\repository\dev\lib\caliburn' lib/caliburn --revision 1

And then the error is:

bzr: ERROR: exceptions.TypeError: sequence item 4: expected string or
Unicode, list found

Traceback (most recent call last):
