If someone configures crypto encryption, 
the notification of new issues shall consider this.

Here is a patch against hg5241:092c4522b3bf

Workaround, just add "crypt=True" as keyword parameter to the call.
An alternative to the patch could be to just add this as an example,
however I think considering the general configuration makes more sense.

(Currently I could not test the setup. Please if someone could test and
then commit.)
