I built firefox from ports 10 day ago and I got everythig OK.

Yesteray I built vlc form ports updating with portupgrade some lib and 
other pors required by vlc.

Now, when I try firefox I get:

[morra at maxy morra]$ firefox

(Gecko:93939): GLib-GObject-WARNING **: cannot register existing type 
`GConfClient'

(Gecko:93939): GLib-GObject-CRITICAL **: g_object_new: assertion 
`G_TYPE_IS_OBJECT (object_type)' failed

(Gecko:93939): GLib-GObject-CRITICAL **: g_object_ref: assertion 
`G_IS_OBJECT (object)' failed
Segmentation fault (core dumped)


Can you help me?


I thank you very much in advance.
