Hello,
I have found a reproducible crash-bug, which only occurs in a strange race condition but could (and did :P) still happen ;)
Reproduce it as follows:
Open a SSH (SFTP) connection to a server and open a file on that server with a extenal texteditor (in my case Sublime Text 3).
Open a connection to a server that is not responding or very slow, I did this via a wrongly configured protocol-url -> just click this link then: winscp-ftps://web78:notarealpassword@webspace34.do.de
Now, while it tries to connect to the server on the unused port 990, save your file in the texteditor.
A crash occurs. This happens in 5.6.2 beta and 5.6.3 nightly.
So long,
Tobias
