Comment 3 for bug 173886

Same problem here when proxying via ssh socks proxy on port 1080 to a server running on 443.

When run directly:
$ pidgin
/usr/share/themes/Blubuntu/gtk-2.0/gtkrc:169: Clearlooks configuration option "progressbarstyle" is not supported and will be ignored.
dns[16016]: Error: Parent requested resolution of an empty hostname (port = 443)!!!
Fallo de segmentación [segmentation fault]

A backtrace:

Program received signal SIGSEGV, Segmentation fault.
