STEPS TO REPRODUCE
1. Use Telegram / OBS / Firefox to share screen in Wayland

OBSERVED RESULT
Nothing "observed", but the journal log is filled with kpipewire_logging: Window not available PipeWireSourceItem(0x5dec6195ed00, id="pipeWireSourceItem", parent=0x5dec6194e070, geometry=8,8 340x0)

EXPECTED RESULT
A window selection dialog pops up.

Comment 1 mooodyhunter@outlook.com 2024-02-04 23:35:27 UTC 
A weird thing is, this bug doesn't occur for a newly-created user.
Is it possible that some related settings are affecting the behavior?
Comment 2 mooodyhunter@outlook.com 2024-02-06 00:05:33 UTC 
After I select a "global theme" in system settings (nothing was selected there beforehand), the portal starts to work without issue.
Comment 3 Nate Graham 2024-02-07 02:29:20 UTC 
Fascinating. Sounds similar to Bug 474639.
Comment 4 Michael Kaplan 2024-02-08 13:45:48 UTC 
I seem to be getting the same. I'm on Fedora 39, KDE 5.27.10, pipewire 1.0.3

Forgot to mention, that I have a global theme set for quite a while(and it is quite an old install, that has been upgraded over time)

lookandfeel packagestructure: Always fallback to default package

If a theme has no metadata.json (which can happen in the 5 to 6
transition period), we would end up with a valid package without
any fallback package. If such a package doesn't contain a certain
file we can now fall back.

SystemDialog: Fallback to default lnf theme
