How reproducible is this?  What were you doing when it crash?

Comment 13 James Boyle 2015-03-09 14:40:12 UTC 
I recently upgraded to Fedora 21 on the client side.  I believe this crash was triggered by logging in to this Fedora 20 system from that Fedora 21 client, but I am not certain.  The system was that the remmina client connected, presented a password prompt, popped up the window, then another window (all black), then both windows would disappear.  When connecting to a Cent 6.6 server, I am able to get a remote desktop, but in a separate window from the remmina window.

Since then, both systems have been updated and restarted.  From F21, I am able to connect to the F20 system now.
Comment 14 James Boyle 2015-03-18 15:35:00 UTC 
I haven't had issues connecting to freenx servers on Cent 6.6 or F20 from my F21 client in recent weeks.

Thank you!
