Most likeky this is because of GLib side change:
https://gitlab.gnome.org/GNOME/glib/-/commit/118265fb976cc14240a366ff820e9960bf4e056c
https://gitlab.gnome.org/GNOME/glib/-/commit/6210a7ea97e12e36118f31ad8c4008ccaea7c1ca

and most likely this is fixed in glibmm side with the below commits:
https://gitlab.gnome.org/GNOME/glibmm/-/commit/b353a8b0afc1aa78f3eec58229f02acd9fab6d3e
https://gitlab.gnome.org/GNOME/glibmm/-/commit/d26083c41219958e802d5da733d4b4d3c342ec89

Please backport the above 2 patches.

glib2-2.89.2-2.fc45
glibmm2.4-2.66.9-1.fc44

Reproducible: Always
Comment 1 Dominik 'Rathann' Mierzejewski 2026-07-22 10:57:46 UTC 
So does subtitleeditor: bug 2504692 .
Comment 2 Mamoru TASAKA 2026-07-22 14:47:35 UTC 
PR https://src.fedoraproject.org/rpms/glibmm2.4/pull-request/3

jd and subtitleeditor both build successfully with the above patched glibmm2.4:

Comment 3 wojnilowicz 2026-07-22 17:48:22 UTC 
I believe #2505218 is related.
Comment 4 Mamoru TASAKA 2026-07-23 02:53:37 UTC 
Since many packages currently FTBFS due to this bugs, I may consider merging the above PR myself with provenpower right.
Comment 5 Tomas Popela 2026-07-23 12:50:06 UTC 
Thank you for the PR Mamoru!
Comment 6 Mamoru TASAKA 2026-07-24 10:47:37 UTC 
Now modified glibmm2.4 is in F45 buildroot, and at least jd and subtitleeditor are buildable.
