failed to import https://git.xiph.org/opus.git

[rillian]

Tried to create an lp branch to follow our upstream git repository today, but the import job failed. The repository in question is https://git.xiph.org/opus.git, which works fine with the command-line git client on my machines.

There's a backtrace in the log message http://launchpadlibrarian.net/117359773/giles-xiph-opus-master.log

Reproduced here for clarity:

This fails with a different error when using bzr-git trunk.
