Crash in GammaRay::ObjectTypeFilterProxyModel<QItemSelectionModel>::filterAcceptsObject() #31

This is what I get when trying to attach to QtCreator on mac: |

@munknex: That's probably another issue. Try starting with "gammaray qtcreator" directly. |

Still a problem. Just checked. |

We might get null-pointers for the 'obj' var in some cases, this is due the way the probe sends out model modification events. These are done in the main-thread, and some of the object may have already been deleted in another thread again, hence resulting in a null-pointer here. This and other multi-threading-related issues should fix #31. Related: bc0aca9

Should be fixed in 2.0 |

Probably related to thread-safety issues amongst our models
