There is no line number in _ibus_dbus_input_context_skeleton_handle_method_call() but I guess invocation == NULL in your case.
I think you use a Flatpak application and I need to know the reproducing steps because sending the NULL object is wrong instead of receiving the NULL object.

Comment 15 Tim Waugh 2024-11-18 12:42:58 UTC
I have no idea what Flatpak application I was using here, sorry.

Comment 16 Adam Williamson 2025-12-02 01:29:55 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It is Fedora's policy to close all bug reports from releases that are no longer
maintained.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 17 Samyak Jain (RedHat) 2025-12-16 17:26:11 UTC
Fedora Linux 41 entered end-of-life (EOL) status on 2025-12-15.

Fedora Linux 41 is no longer maintained, which means that it
will not receive any further security or bug fix updates. As a result we
are closing this bug.

If you can reproduce this bug against a currently maintained version of Fedora Linux
please feel free to reopen this bug against that version. Note that the version
field may be hidden. Click the "Show advanced fields" button if you do not see
the version field.

If you are unable to reopen this bug, please file a new report against an
active release.

Thank you for reporting this bug and we are sorry it could not be fixed.
