Comment 13 Adam Williamson 2025-12-02 01:38:30 UTC

This message is a reminder that Fedora Linux 41 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 41 on 2025-12-15.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained.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 '41'.

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 41 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.

Comment 14 Mr. Beedell, Roke Julian Lockhart (RJLB) 2025-12-02 14:40:08 UTC

This doesn't reproduce, and no upstream report exists. Therefore, I'll close as WORKSFORME. Please confirm whether that's accurate, or EOL is, because I've confirmed with:
