This bug has been fixed upstream, see https://github.com/matplotlib/matplotlib/pull/2307.
The fix will be part of the upcoming bugfix/minor release 1.3.1 of matplotlib. I assume unstable will be updated to 1.3.1 after it is released? After/if it is updated this bug can be closed. best, Tobias -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
