Public bug reported:
After the SSL rebuild, Remmina is crashing with a segmentation fault
when trying to connect to a Windows Server 2019 machine using RDP.
I tried removing the sensitive data from this backtrace (#7 has
TERMSRV/XXX.XXX.XXX.XXX), hopefully everything sensitive was removed.
The full backtrace is:
