Bug#903646: libwinpr2-2: remmina crashing on reconnect

[Markus Frosch]

Package: libwinpr2-2
Version: 2.0.0~git20180411.1.7a7b1802+dfsg1-2
Severity: normal

Hello Remote maintainers,
lately remmina keeps crashing when the connection needs to be
reconnected.

I don't think this is a bug with remmina, but libwinpr2.

It happens on RDP sessions with Windows Server 2012 and 2016, here is a
backtrace I collected.

Please tell me if I can supply more details!

Regards
Markus
