I just hit this one also. If you say how to debug it, I will be happy to help here. It happened with both feisty's bzr-svn and current (today's) .3 branch. bzr is at 0.15-0ubuntu2.

Thanks.

[Jelmer Vernooij (jelmer)]

This was fixed in 0.3.3 IIRC

[Václav Šmilauer (eudoxos)]

I updated bzr to make sure to 0.17.0candidate1 and have 2 days old 0.3 branch of bzr-svn (https://code.launchpad.net/~jelmer/bzr-svn/0.3 -as before).

The same error as before. However, I did "bzr unbind", then tried "bzr push" to saved location (failed, saying "No new revisions to push."). Finally, for the heck of it, since it should not work on unbound branches, I tried "bzr commit" and it seemed to work ("Commited revision 17."). But when I checked svn repo, it was really NOT commited!

Then I tried "bzr push", it exited with the following:

I am sorry to flood you with those reports. (Again, can help you debugging that in any way you tell me.)

[Benjamin Heitmann (benjamin-heitmann)]

I run into exactly the same bug, when doing the same things
(committing the changes to the bazaar repository back to the orginal subversion repository).

All tests of "bzr selftest svn" run successfully.

I am using the following versions:
bzr 0.18
bzr-svn 0.3.5
python 2.5.1
subversion 1.4.3 patched with http://samba.org/~metze/subversion-1.4.0-metze-python-bindings.patch
and the compiled with swig 1.3.25

Everything running on Mac OS X with fink.

The error I get is this one:
bzr: ERROR: exceptions.AttributeError: 'SvnRepository' object has no attribute '_serializer'

This bug has been fixed in 0.4.0, not 0.3.5 (it can't be fixed in the
0.3 branch, though the error message could be improved). "bzr commit"
from a checkout ("bzr co ...") does not work in 0.3.5.

  status fixreleased

Okay, I just saw the update of the bzr-svn page at http://bazaar-
vcs.org/BzrForeignBranches/Subversion

It states that bzr-svn 0.4 works with bazaar 0.19, so I guess it does
not work with 0.18.

As 0.19 has not been released, are you referring to the
https://launchpad.net/bzr/bzr.dev
branch ?

cheers, Benjamin.

Yep, exactly - that branch should work.

Cheers,
