I cannot reproduce your backtrace. Many X11 applications does not call CloseMessageProc() and I need to know which X11 application you tried when you get your backtrace. _free_x11_iconn_from_id() works fine in my tests so it might be a timing issue.

*** Bug 2365588 has been marked as a duplicate of this bug. ***
I think I was switching ibus input methods at the time it failed. I don't remember seeing this issue recently and I doubt it's still meaningful after 1.5.32-2.
This message is a reminder that Fedora Linux 42 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 42 on 2026-05-13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a 'version' of '42'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, change the 'version' to a later Fedora Linux version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see it. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 42 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora Linux, you are encouraged to change the 'version' to a later version prior to this bug being closed.
