Throws TypeError: 'NoneType' object is not iterable on load

[cyian-1756]

If I try to load a level the following error is thrown

Traceback (most recent call last): File "/usr/share/panda3d/direct/showbase/EventManager.py", line 52, in eventLoopTask self.doEvents() File "/usr/share/panda3d/direct/showbase/EventManager.py", line 46, in doEvents processFunc(self.eventQueue.dequeueEvent()) File "/usr/share/panda3d/direct/showbase/EventManager.py", line 103, in processEvent messenger.send(eventName, paramList) File "/usr/share/panda3d/direct/showbase/Messenger.py", line 327, in send self.__dispatch(acceptorDict, event, sentArgs, foundWatch) File "/usr/share/panda3d/direct/showbase/Messenger.py", line 412, in __dispatch method (*(extraArgs + sentArgs)) File "main.py", line 1261, in load self.current_grass_textures) File "/home/wil/code/koparka/sqliteloader.py", line 121, in LoadScene row = dict(cur.fetchone()) TypeError: 'NoneType' object is not iterable :task(error): Exception occurred in PythonTask eventManager Traceback (most recent call last): File "main.py", line 1817, in <module> base.run() File "/usr/share/panda3d/direct/showbase/ShowBase.py", line 2986, in run self.taskMgr.run() File "/usr/share/panda3d/direct/task/Task.py", line 510, in run self.step() File "/usr/share/panda3d/direct/task/Task.py", line 467, in step self.mgr.poll() File "/usr/share/panda3d/direct/showbase/EventManager.py", line 52, in eventLoopTask self.doEvents() File "/usr/share/panda3d/direct/showbase/EventManager.py", line 46, in doEvents processFunc(self.eventQueue.dequeueEvent()) File "/usr/share/panda3d/direct/showbase/EventManager.py", line 103, in processEvent messenger.send(eventName, paramList) File "/usr/share/panda3d/direct/showbase/Messenger.py", line 327, in send self.__dispatch(acceptorDict, event, sentArgs, foundWatch) File "/usr/share/panda3d/direct/showbase/Messenger.py", line 412, in __dispatch method (*(extraArgs + sentArgs)) File "main.py", line 1261, in load self.current_grass_textures) File "/home/wil/code/koparka/sqliteloader.py", line 121, in LoadScene row = dict(cur.fetchone()) TypeError: 'NoneType' object is not iterable

It looks like there's a missing record in the sqlite database (or it's failing to load find it). I'm looking into it, but so far a was not able to reproduce it.
