Package: bzr
Version: 2.6.0+bzr6595-1
Severity: important

Dear Maintainer,

Committing to a bzr repository over sftp appears to now be broken.  (It
wasn't broken a month ago, or so.)

This is quite reproducable:

  ~$ bzr init foo
  ~$ bzr co sftp://localhost/~/foo bar
  ~$ cd bar
  bar$ touch a
  bar$ bzr add a
  bar$ bzr ci -m ""
  **BOOM!**

It seems that bzr+ssh:// URLs still work, though.

Here's the Python dump:


bzr: ERROR: exceptions.TypeError: Expected unicode or bytes, got
<read-only buffer for 0x7f05409fd8a0, size 5242880, offset 0 at
