When I set the SSH Client to OpenSSH, I get this error:
'ssh-agent' failed with code -1: System.NullReferenceException: Object reference not set to an instance of an object.
()
This message also appears every time I start SourceTree. As for the rest, everything appears to be working (as best as Atlassian can get it, I suppose).
Windows 10 FCU
SourceTree 2.4.7
Mercurial 4.4.2 (not embedded)
OpenSSH 0.0.24 (same as the built-in windows feature, but with bugs fixed)
