The load-finished signal has a GError* argument which is meant to signify whether the loading was successful. However many of the places in ClutterTexture that emit this signal directly pass their 'error' variable which is a GError** and will be NULL or not completely independently of whether there was an error. If the argument was dereferenced it would probably crash. The test-texture-async interactive test case should also verify that the ::load-finished signal is correctly emitted.
