pkg-kde-tools vcs import fails

Asked by Felix Geyer

This branch fails to import:
https://code.launchpad.net/~vcs-imports/pkg-kde-tools/debian

Converting the git branch to bzr locally works fine (using bzr-git)

Traceback (most recent call last):

What version/revno of bzr-git are you using?

With bzr-git r1212, importing from scratch works, but not an incremental import
$ bzr branch lp:~vcs-imports/pkg-kde-tools/debian
$ cd debian/
$ bzr pull lp:~vcs-imports/pkg-kde-tools/debian
bzr: ERROR: An inconsistent delta was supplied involving u'qt-kde-team/2', 'qt-kde-team/2'
reason: New id is already present in target.

You're right, importing from scratch works but updating the vcs-imports branch fails with the same error as on launchpad.

So what are our options?
Recreate the branch and hope it doesn't fail again in the future?

Yes, I think recreating the branch is the only option. It's possible that the remote branch was altered, leading to this issue, or it could be a bzr-git problem. Right now, we don't have enough information to know.

Can you help with this problem?
