Hi,
I did not have all that much time lately.
But my problem still exists. x2goclient crashes sometimes (not all of
the time though), when trying to connect to the server.
This does still happen with the new versions of x2goclient and server
released yesterday.
In Chemnitz Heinz suggested to try using an older libssh to see if the
problem was located there, but that didn't help as well.
I have created a backtrace (still missing some debug symbols, I will
see, what debug packages are still missing).
Can anyone help me with it?
Oliver
