Created Unassigned: StackOverflowException thrown on Connect() [2620]

During a test I wanted to force an exception to be thrown while connecting to my SFTP server.

To my surprise the exception took down the whole process when I added an uncerscore ("_") to my password.

The StackOverflowException is thrown after a couple of minutes:
"An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll"

I am using SSH.NET.2014.4.6-beta2 taken from Nuget.

I am connecting using a combination of username/password and a private key.
