[gtk-vnc-devel] Segfault

[Jonh Wendell <jwendell gnome org>]

Hi, folks.

I'm getting a segmentation fault in vinagre, related to gtk-vnc:

-I connect into 200.100.100.246, type my password, the connection is OK;
-I connect into 200.100.100.191, type my password, and vinagre crashes.

I'm attaching the gdb log, i guess it can be useful.

Any idea?
