Guake: Guake crashes - Ubuntu 20.04

[tryfon]

Guake was working fine but at some point started consistently crashing after it starts. No idea what causes it. Find attached my dmesg log. Ubuntu 20.04, Guake 3.7.0 installed through pip3.

The same happens in Ubuntu 19.10, after running fine for more than 4 months.

The following assertion triggers just before the SEFGAULT:

/usr/lib/python3/dist-packages/gi/overrides/Gtk.py:1630: Warning: g_object_freeze_notify: assertion 'G_IS_OBJECT (object)' failed
  return _Gtk_main(*args, **kwargs)
Segmentation fault (core dumped)

I've checked the apt update logs but the only GTK-related packages that have been recently updated are libwebkit2gtk-4.0-37, libjavascriptcoregtk-4.0-18, and gir1.2-javascriptcoregtk-4.0- Not sure if they are related.

I see the same on Manjaro Gnome after updating just now - let me know what info if any I can provide to help debug this.

EDIT to add: I'm now getting a different output after restarting

VTE:ERROR:../vte/src/vte.cc:3336:void vte::terminal::Terminal::process_incoming(): code should not be reached
Bail out! VTE:ERROR:../vte/src/vte.cc:3336:void vte::terminal::Terminal::process_incoming(): code should not be reached
Aborted (core dumped)

When I then start to run guake again I get a segfault with no error messages, then on the third attempt I again get the Gtk.py related message above. This is on Guake 3.7.0, VTE 0.60.2, Gtk 3.24.20

Same in ubuntu 18.04, crash log attached if that helps.

Guake Terminal: 3.7.0
VTE: 0.52.2
VTE runtime: 0.52.2
Gtk: 3.22.30

Might be related to https://github.com/Guake/guake/issues/1749#issuecomment-632189285.
Try the "solution" I posted in the linked comment, to see if it works for you.

Indeed this did the trick, thanks!

Let me close this as duplicate of #1749.
