#1281 Error with IP (or Port) in connection time

[Max]

I create VNC file (name.vnc) of host for fast connection. IP of host:
192.168.1.101
And Port (default):
5900
("host=" and "port=" strings in file respectively)

From time to time (~1/10), when I run VNC file, I got one of this error (in attachment). Attention on IP:PORT in title of error message window.

I can confirm this error is in 2.7.10 too. TVNC seems to mangle the url randomly even when its from the Connection Open dialog box. It may happen every 10 or 20 opens.
