[Bug 1666178] Re: Qt & GTK apps are crashing with SIGABRT in mir_create_modal_dialog_window_spec() due to NULL parent pointer

[Daniel van Vugt]

Seems like the right answer in some cases might be:

MirWindowSpec*
mir_create_dialog_window_spec(MirConnection* connection,
                              int width, int height);


** Summary changed:

- Legacy apps are crashing with SIGABRT in mir_create_modal_dialog_window_spec() due to NULL parent pointer
+ Qt & GTK apps are crashing with SIGABRT in mir_create_modal_dialog_window_spec() due to NULL parent pointer

** Description changed:

- ubuntu 17.04 Unity 8
- 
- synfigstudio crashed with SIGABRT in
- mir_create_modal_dialog_window_spec()
+ Qt & GTK apps are crashing with SIGABRT in
+ mir_create_modal_dialog_window_spec() due to NULL parent pointer
