bzr 0.11.0 on python 2.4.3.final.0 (linux2)
arguments: ['/usr/bin/bzr', 'branch', 'svn+https://svn.sandcat.nl/repos/sws/trunk']

This is on Dapper, with jelmer's python-subversion, python2.4-subversion and libsvn0 packages installed.

The repo branched is a publicly readable one, so this should be reproduceable.

I get the same error when trying to branch mplayer trunk
bzr branch svn://svn.mplayerhq.hu/mplayer/trunk mplayer-trunk

So this is not dependent on https....

I have exactly the same problem with the following svn trunks:

http://svn.scipy.org/svn/numpy/trunk (using branch svn+http://svn.scipy.org/svn/numpy/trunk numpy.bzr)

http://svn.scipy.org/svn/scipy/trunkbzr (using branch svn+http://svn.scipy.org/svn/zcipy/trunk scipy.bzr)

with bzr 0.12.0 on edgy and last bzr.svn (rev 230).

It looks like for some reason, after the step "fetching svn revision is complete", the variable self.revisions in logwalker.LogWalker.follow_history has the first revisions removed (not always the same number: from 0 to 6 when branching everyting from numpy, from 0 to 18 when branching everything from scipy).

[David Cournapeau (david-ar)]

I don't know if this is relevant, but the SvnBranch._generate_revision_history is called twice when trying to branch, and the self.revisions variable has its first revisions removed only at the second time

Ok, I upgraded bzr.svn and bzr to 0.13, and now, I have other kind of errors:

DBError: (5, 'Input/output error -- read: 0x8381d40, 16384: Input/output error')

I first thought it was the same kind of errors, but after having debug an other problem in bzr, I realized that this error is specific to my setup, where my home is on NFS share. Should I open a new bug ?

Please do. This'll most likely be fixed once we trade bsddb for sqlite3.

Cheers,
