latest thunderbird update (52.1.1) broke my thunderbird/enigmail configuration, resulting in thuderbird hanging while "creating email", only for encrypted emails.

[ianni67]

It happens since a couple of days. Every time I send an encrypted email, Thunderbird hangs on "creating email". It hangs forever. I have to close the window and re-create the message (also loosing the text, so I have to copy it first). Then it usually works, but will hang at the next message.

I run Ubuntu 16.04.

I found other people having the same issue:

This problem is very annoying, please help-

This sounds like a duplicate of bug 1713486 so I'm marking it that way.
