[gtk-vnc-devel] [patch] fix a crash

[Jonh Wendell <jwendell gnome org>]

Hi, folks.

I just committed this trivial patch, that avoids a crash if we
disconnect right after connect.

And yes, this [new] crash event was introduced by my last patch for
pixel_format stuff :P

Cheers,

Do more checks if connection is still alive in initialisation.
This fix a crash when closing the connection right after connecting.
