Hey, I can reproduce this issue and also have an idea what is wrong in the code. Encrypt uses the async method of gnupg and sign+encrypt till using the old non-async method. It seems like gnupg has changed something in the last version(s) and the async method breaks somehow. I've seen this issue also for other parts. I'll try to create a patch the next weeks.
