random crashes of gnome-characters

[Vadim Sukhomlinov]

Usually just a one-line record in syslog:

Status changed to 'Confirmed' because the bug affects multiple users.

The "MEMORY-ERROR" message appears in ~/.xsession-errors rather than syslog for me, but it's also the same random crashing of gnome-characters that causes the application to suddenly exit; relevant lines in ~/.xsession-errors:

Gjs-Message: 17:38:44.610: JS LOG: Characters Application started
Gjs-Message: 17:38:44.782: JS LOG: Characters Application activated

I would like to add that the error message is also printed to `STDOUT` when the application is run in a terminal.

`gnome-characters` appears to be very unstable under Ubuntu 22.04; I have never managed to have it running more than a couple of minutes. Sometimes it will crash with a segmentation fault without printing anything about `GSlice`.

Exactly the same issue here. To copy and paste a few special characters you need to run the application over and over again. This is very cumbersome.
