Comment # 8 on bug 1039471 from Sebastian Ernst

Ok, I just pulled in the latest updates from the regular update channel on one
of my machines, resulting in the following package versions: 

ernst@linux-eh50:~> rpm -qa | grep -i thunder
MozillaThunderbird-52.2.1-41.12.1.x86_64
MozillaThunderbird-translations-common-52.2.1-41.12.1.x86_64
ernst@linux-eh50:~> rpm -qa | grep -i enigmail
enigmail-1.9.8-2.6.1.x86_64

Things are back to normal and work as expected. 

I can also test the factory version, if you'd like. From which repository
should I take it?
