+        self._con = sqlite3.connect(db_path)
+        cur = self._con.cursor()

I'd avoid abbreviations if possible: self._connection and cursor.

+        cur.execute('insert into places values (?, ?, ?, ?, ?, ?)', \
+                    (place.uri, place.title, place.bookmark,
+                     place.gecko_flags, place.visits, place.last_visit))

This will break or have unintended effects if the schema changes.
Specifying the names of the fields will make it more robust:

'insert into places (uri, title, bookmark, gecko_flags, visits,
last_visit) values (?, ?, ?, ?, ?, ?)'

+        cur = self._con.cursor()
+        cur.close()

Should we use try...finally blocks so we don't leak open cursors?
Also, we could use the with statement from future.

+        place.uri, place.title, place.bookmark, place.gecko_flags, \
+            place.visits, place.last_visit = row

If we are going to use row as a tuple, we should specify the columns
we are querying in every select statement, so code is more resilient
to schema changes. If row could be used as a dict, then it wouldn't

+    COL_ADDRESS = 0
+    COL_TITLE = 1

Should be private?

+        self.handler_block(self._change_hid)
+        self.props.text = uri
+        self.handler_unblock(self._change_hid)


+        self.handler_block(self._change_hid)
+        self._address = address
+        self.handler_unblock(self._change_hid)

Do we really need to block the signal handler here? Same with self._title.

+        list_store = gtk.ListStore(str, str)
+        for place in places.get_store().search(self.props.text):
+            list_store.append([place.uri, place.title])

Might be interesting to implement a descendant of ListStore that
accesses directly the places db, so that the user can scroll down past
the maximum number of search results.

+    def __focus_in_event_cb(self, entry, event):
+        self.handler_block(self._change_hid)
+        self.props.text = self._address
+        self.handler_unblock(self._change_hid)

Could we avoid this code duplication?

+        path, col_dummy, x_dummy, y_dummy = \

I've been using col_ for dummies and pylint seems to like it.
