I've got a test instance using the sqlite backend. I recently updated to current master and tried to run dbupdate. I received the error below.

(mediagoblin-dev) ~/mediagoblin-dev $ bin/gmg dbupdate

It would seem Paste now supports Python3 (​source here). If we move back we can solve some issues we are having with gunircorn such as the one in #978.

It would seem since version 2.0 of Paste it's had experemental python 3 support, the 2.0.1 and 2.0.2 build on that.

Re-processing a video that failed to be processed gives the following traceback:

I'll need to prepare a smaller video that has similar metadata, but the video I was uploading on is here:

​http://www.sturm.com.au/2015/talks/rock-your-emacs-libreplanet/rock-your-emacs.webm

I'm assuming that the issue is that if there is any date information, MediaGoblin assumes the full date is supplied. This video only has a year specified I think, so the get_month() returns zero.
