Test case (run with GTK_DEBUG=interactive) (472 bytes, text/x-csrc)

Test case (run with GTK_DEBUG=interactive)

GtkInspector causes a crash when you respond (attempt to close, press Open, etc.) to a FileChooserDialog. Any custom "response" signal handlers are run successfully, so the crash happens at some point after that.

This started happening since I upgraded from 3.16.x to 3.18. Tested on Arch Linux with GTK+ 3.18.2.

To test:

1. Compile the attached code.
2. Run with GTK_DEBUG=interactive so you get GtkInspector.
3. Press Escape (or click the Close button) on the file chooser dialog.

Expected behaviour: "Hello" is printed. Dialog stays open.

Actual behaviour: "Hello" is printed. Segfault.


Following is the backtrace. Unfortunately for some reason the glib symbols are incomplete.
