Maybe no one has bothered. Maybe file one yourself. If you believe it to be an issue on the Arch side.
[joekamprad@buildsystem-kde ~]$ dolphin
Cannot initialize model with data QJsonObject(). missing: QJsonValue(string, "urls")
ark.kerfuffle: Could not detect mimetype from content. Using extension-based mimetype: "application/vnd.efi.iso"
i got this when starting dolphin from terminal and open contect menu on a iso file.
As long as i do not know what is the cause hard to fill a report…
Downgrading dolphin and dolphin-plugins also doe snot bring the option back…
could be some mimetype issue from the output i got…
Let me test it to. Maybe if I take a look at the dolphin-plugins code, I can uncover a bit more.
i got the issuer tracked down…
https://archlinux.org/packages/extra/x86_64/shared-mime-info/
downgrading shared-mime-info to 2.2+13+ga2ffb28-1 (funny versioning…) solve the issue.

I tried downgrading and it didn’t make any difference?
you will need to reboot i bet and make sure the iso mount option is still enabled
May be this is it? Where do i see that under?
extra/shared-mime-info 2.2+13+ga2ffb28-1
is what i have installed

I don’t see this under context menu?
if using current release fresh install of kde you will not have dolphin-plugins package installed by default.
I installed that too.
Edit: Okay maybe i removed it again since it wasn’t working. I’ll check.
Edit2: Okay i have it now.

I can confirm that downgrading shared-mime-info to that version works for me. Now who would I report this to, kde, arch, whoever maintains shared-mime-info? I’m not sure if shared-mime-info is working as intended and the dolphin plugin needs to be updated which I could probably do myself or if this is a regression in the package / packaging.

no clue tried to really track down… but it looks like an issue with shared-mime-info changes.
i reported on arch already…
but seems it is something kde have to fix

Ok, and according to that arch bug report. Someone has already filed a bug report with kde. Guess itbwill be resolved one way or another.
Weird thing is, this is still working for me. I wonder if it has anything to do with it coming from ALHP (totally forgot I was using it on this machine)
It should be the same pkg, just compiled with optimized flags.

We’ve kinda settled on shared-mime-info being the offending package. What version of that are you running?

i have uploaded it here if you really want to test … better is to wait for official fixed version…
