Take a look at the code for the Democracy Player.  They have already
solved the open-uri bug in their own code.  I don't know if their method
is sound, but whatever they did, it works.

>From MozillaBrowser.pyx:
"Here's the deal on the open-uri callback hack:

GtkMozEmbed doesn't define the open-uri callback correctly.  The uri
value is declared as a gpointer, instead of a string.  It's not a
problem in C but it doesn't work in Python.

To get around this, we declare a C callback to handle things.  Since
this callback is coming straight from the C code, we need to acquire the
python GIL or we'll segfault.  Because of this, we can't create any
local python object because they will be DECREFed at the end of the
function -- after we've given back the GIL.  To make things less messy,
the C callback invokes OpenUriCallback to do most of the work."
