Segfault when using GTK templates
I wrote app which uses GTK templates(set_template, bind_template_callback_full, bind_template_child_full, init_template and get_template_child) for UI generation.
In app runtime callback registered via bind_template_callback_full is causing segfault when invoked second time.
I have digged into binaries of pygobject and found out that when callback called second time
closure->function is null, which cause
PyObject_CallObject to crash.
Also I found out that first time when callback is called
closure->function is freed inside
What do not understand - is why
closure->scope is set to
GI_SCOPE_TYPE_ASYNC, since I do not use async code in app at all.
Note: Also what I noticed is that callbacks does not receive any arguments.
Some useful info:
- OS: Elementary OS 5.1.3(Ubuntu based)
- Python: 3.7.5
- and bug works with build from repo(9cdbc56f).
