'bzr branch' for a svn branch bails out

[Mikhail Sobolev]

I'm trying to import a svn branch at https://user:password@host/path/to/repo/branches/branch, the following command bails out:

bzr branch https://user:password@host/path/to/repo/branches/branch

bzr: ERROR: exceptions.TypeError: a2b_base64() argument 1 must be string or read-only character buffer, not None

Is there some public repository that you can reproduce this with?

[Mikhail Sobolev (sa2ajj)]

I tried the trunk for the very same repository (and the trunk does not require authentication). It fails with the same error (see at the end). I start to wonder if there's something wrong with my installation... What information could I provide to help the investigation?

Can no longer reproduce this with the current development version.

[Mikhail Sobolev (sa2ajj)]

Just to make sure what environment I should use: latest bzr (bzr.dev) + latest bzr-svn?

bzr-svn from http://people.samba.org/bzr/jelmer/bzr-svn/bzr.dev - I
wouldn't recommend using that for any production code though.

Cheers,

For what it's worth, the problem does not manifest itself on my computer with the latest bzr, bzr-svn and python 2.5.
