[Pkg-bazaar-maint] Bug#463909: bzr: Internal error with "bzr check"

Package: bzr
Version: 1.1~rc1-1
Severity: normal

Dear bzr maintainers,

I am not quite sure if this is a bug in bzr on the bzr-svn plugin, I'm
reporting it to bzr based on the Python traceback.

On one of my machines, "bzr check" fails with an internal error.  The
branch uses a rich-root format shared repository, the "upstream" branch
is a checkout of SVN upstream, and "packaging" branch is originally
branched from "upstream".

There were also some other complicated operations to this branch, such
as accessed by different versions of bzr (my home directory is mounted
in both Debian and Ubuntu), and pulling from another branch over
bzr+ssh:// protocol.  I can not reproduce this error in another unstable
machine that installs the same bzr packages and uses a very similar
repository/branch layout, but on this machine it's 100% reproducible.
It seems this doesn't affect my daily use of this branch, however.

I'm putting the error and the output of "bzr info --verbose" at the end
of this mail.  I realize rich-root is no longer the default format, but
I'd appreciate if a fix or workaround can be provided.  If you needs
more information, please ask.

Thanks,
Ming
