Did you by any chance accidentally click on the tooltip instead of a menu item?
Unfortunately by the time I'd gone through all the crash reporting process, I couldn't remember exactly what I'd done apart from clicking the window menu button. So although it seems unlikely that I'd have clicked a tooltip, I can't be certain.
That's okay, I was just asking because that bug is similar and was fixed recently.
It's possible that the window has been closed. Although it's hard to say without a complete backtrace. Can you install debug symbols and submit a new backtrace? If you install debug info packages, coredumpctl gdb should provide a backtrace with debug symbols as long as the coredump is still present. Also if you find a reliable way to reproduce the crash, please let us know.
I'm afraid that I can't find any clear instructions as to how to install debug symbols on Debian. I also have only seen the crash once, so it wouldn't necessarily help in any case.
