tilix froze after closing a tile and appended hundreds of millions of erros on .xsession-errors

Hi

I was using tilix with two pages. One had 6 tiles and other three. When I tried to close one tile in the second page, tilix froze. I opened xterm and noticed it was writing data to disk at very high rates, approximately 50 MB/s on .xsession-errors. I killed the tilix process and saw the log file had nearly 6 GB and more than 100 million lines!

The error messages are:

(tilix:4880): Gtk-CRITICAL **: 01:13:09.170: gtk_widget_get_parent: assertion 'GTK_IS_WIDGET (widget)' failed

I'll upload the compressed log file here. While it appears to be small, it has 6 GB, so be sure there is enough space to decompress it.
