 Replying to [comment:11 c.herbig@…]:
 > Would it help at all if I offered to take maintainership (along with
 open maintainer)?  I'm not really a programmer, but I am interested in
 keeping this and goffice up to date with the latest point releases,
 especially when updates deal with file compatibility.

 While it wouldn't immediately help with this ticket, it would certainly
 help to speed up future updates. If nobody has taken care of this by
 Thursday, I'll find some free time to do it.
