Please keep in mind that these appear as emails in a crowded inbox,
so the subject line can be a good place to put valuable context.

Can you reproduce this with 3.8.2 from experimental?

If so, please report it to bugs.freedesktop.org, following
instructions from [1], and let us know the bug number so we can track
it.

If 3.8.2 does not reproduce the problem, we can try to find the patch
that fixed it and apply the same to wheezy.  So either result is
progress.

Thanks for reporting and hope that helps,
Jonathan
