Comment 1 for bug 160232

Thankyou for the report. I've filed a bug against the bzr-svn plugin.

Can you determine at all why it's not able to open the svn url? Is
/home/mez/devnull/branches/trunk the svn branch itself, or a bzr
branch? If the former, you might need to give a file:/// url
explicitly? (I'm just guessing, I haven't used bzr-svn much.)
