bzr crashed with AssertionError in provide()

[Paul Gevers]

Binary package hint: bzr

Recently we created a new project on launchpad (remote-torrent), and I am trying to figure out how to build debian packages from that using bzr functionality (instead of doing it manually).

Now there is no tar ball yet of a release and bzr went out to fetch some. The following is the result:

paul@stromboli ~/offline/remote-torrent/trunk $ bzr-buildpackage
Building using working tree

Purging the build dir: /media/home/paul/offline/remote-torrent/build-area/remote-torrent-1.3.2

I just hit this bug in 11.10. Will apport-collect information be useful?

Can you reproduce this with bzr-builddeb trunk? It no longer has this line.
