Ouch. Dang, I thought my tests covered that, obviously not :-/
Fixed (and also added --check={crc64,none} while I was there).

Not sure what you mean here, I'm using bzr (based on
bzr+ssh://bazaar.launchpad.net/+branch/pristine-tar/) not git :-}
https://code.launchpad.net/~vcs-imports/pristine-tar/trunk is an import
from git://git.kitenet.net/pristine-tar/ though so there should be a
way...
In the mean time, I've pushed my branch at
bzr+ssh://bazaar.launchpad.net/~vila/pristine-tar/677250-parse-xz or
https://code.launchpad.net/~vila/pristine-tar/677250-parse-xz/ for human
readers.
I'm also quite a noob at packaging but I'm eager to learn...
Vincent
P.S.: I'll be in vacations for a week starting tonight.

pristine-tar (1.26) UNRELEASED; urgency=low
* pristine-xz: Use xz --robot to extract information from xz files,
- avoiding the need to do more expensive guessing. Will also later
- allow supporting files needing --block-split (once upstream xz
- provides that option; a patch has been submitted).
+ avoiding the need to do more expensive guessing. Support --block-list
+ when available to reproduce multi blocks files.
Closes: #677250 Thanks, Vincent Ladeuil
