[Gpg4win-devel] Gpg4win 3.0.0beta187: Outlook 2013 crashes while sending encrypted email

[rpr //]

Hello!

I tested Gpg4win 3.0.0beta187 on MS Windows 10 Pro. x64 with
MS Outlook 2013 x86 (with all current updates installed).
It has GpgOL 1.4.0 and uses PGP/MIME for encryption.

I noticed a problem while sending an encrypted email: after I click
the Send button and confirm the recipients' certificates, Outlook 2013
crashes and then restarts. The encrypted message stays in the Outbox
and can be sent successfully afterwards (with Send/Receive action).

The following error is logged in the Event Log:
