the ending line:
Assertion failed: (stream->flags.writing), function es_flush, file estream.c, line 1873.

startup specific stuff for 2.1, but the rest is relatively unchanged (and generally
Unfortunately, I need to go back to gnupg 2.0 in order to be able to continue to
work/send email, but I'll try to answer questions if I can.
