You cannot rely on the value of cru->uri in cell_renderer_uri_activate.
Note that cell_renderer_uri_activate has a path as an argument, you can
use this path to get the data from the model. But of course the cell
renderer doesn't know from which column it should get the data. So a
better approach may be to add an "activated" signal to your cell
renderer and emit that, and write a nice signal handler. See
gtkcellrenderertoggle.c for an example.
