Comment 3 for bug 569360

This is correct behaviour. bzr-svn doesn't push merged revisions but only the mainline by default so when you pull down the repository later it can't fetch the merged revision and since it hasn't fetched them it can't display them.

If you push the merged revisions to e.g. branches/foo in the repository it works fine afterwards. Alternatively you should be able to set push_merged_revisions = True
