Going to the following site causes an immediate crash of all Galeon windows
(you have been warned):

Running Galeon from the console and doing this gives me the error:


** ERROR **: file io-ico.c: line 342 (DecodeHeader): assertion failed:
(State->LineBuf != NULL)
aborting...
Aborted


It seems like this is the likely cause, but I can't tell, since running
Galeon from the console normally causes frequent GTK warnings. I checked in
Mozilla and this problem seems to be isolated to Galeon.
