I would just like to add that this is not our prefered solution: We would prefer to be using enigmail as a debian package rather than relying on 3rd party sources, and we do believe that it is a plugin of particular importance since it's the only means (afaik) that provides thunderbird with OpenPGP capabilities. But we can't risk having colleagues that do not have command line knowledge losing access to secure communication for a whole day like we just have, so until this issue is resolved, that's what we'll be doing.
However, it seems that this discussion is more likely to be continued at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=869774 which is the thread of the enigmail bugreport. Greetings, Shevek
