d-feet crashed with AttributeError in cursor_changed_handler()

Got the same problem repeatedly.

The same problem while browsing almost any dbus api..

I have the same problem too

Right clicking a couple of times in a row on a method name should reliably bring up this.

Just expanding a couple of items in the right pane brings this up continously.
Can't we have simply a "if node != None:"...

same problem with a good portion of the things I expand in the right pane

The traceback being thrown also confuses apport, which reports that D-Feet has crashed (even though it hasn't).

Could you retry with last version (0.1.10-1)?

Yep, still the same crash, reproduces every time.

The problem still exists could it be just apport being too sensitive about python crash?

Bug was an incorrect implementation of TreeModelIface (get_iter would never stop returning iterators)

Fix is:
diff --git a/dfeet/introspect_data.py b/dfeet/introspect_data.py
index f68ed19..df5ad85 100644
--- a/dfeet/introspect_data.py

Patch sent to John Palmieri

(The reason this doesn't crash or actually cause a problem is PyGTK catches exceptions in signal handlers and continues execution. In this case since the function should not return None anyway the behaviour was correct for GTK+).

should return None anyway

This bug was fixed in the package d-feet - 0.1.10-2ubuntu1
