Assertion failed. Program crash.

When I navigate to only one specific folder on my server (/var/misc/httpd), WinSCP3 crashes and gives me the following error windows:

Assertion failed: State != rsUndef, file D:\Martin\Projekty\WinSCP2\core\RemoteFiles.cpp, line 979

Then this:

Abnormal program termination

I have posted screenshots here:
First error: <invalid hyperlink removed by admin>
Second: <invalid hyperlink removed by admin>

As far as I can tell, this only happens when I navigate into that folder ONLY. Problem is that all of my website files are in that folder. I am running the latest WinSCP 3.3.

Any help you can give would be immensely appreciated.

Please post a log file.
Also you may try SFTP protocol instead of SCP.
