Comment 3 Rene Richter 2015-06-25 14:28:47 UTC

(In reply to Rene Richter from comment #0)
Maybe the information is useful: I did not have the correct S/MIME client-certificate installed on my machine at the time.

Comment 4 Andre Heinecke 2015-06-26 11:04:38 UTC

This was fixed Git commit be886ddf9397ab1ee40a075a1ee34c5c42dea038

It is also fixed upstream in libassuan:
