avahi-discover crashes if row is unselected

[james_w]

Hi,

In

https://bugs.launchpad.net/bugs/230337

a user reported that avahi-discover crashed for them.

Traceback (most recent call last):

File "/usr/bin/avahi-discover", line 64, in on_tree_view_cursor_changed

(name,interface,protocol,stype,domain) = self.treemodel.get(iter,1,2,3,4,5)

TypeError?: iter must be a GtkTreeIter?

I believe the cause of this was the a row was unselected, meaning that get_selection() returned None for iter, which then was used improperly in treemodel.get()

The attached patch should prevent this from happening. Please consider applying it.

Thanks,

James
