Unresolved mime type (KDE)

Dear all,

when I open an image with gwenview, I get a long list of warnings about unresolved mime types:

> gwenview some-image.jpeg

If I understand the warnings correctly, they mean that gwenview is associated with those file types, but cannot open them. What options do I have to get rid of the warnings other than to manually create an entry for each of those in the system settings Applications → File Associations? (I don’t remember ever having to open one of those file types.)

Thank you for your help!

This is of no help. But yes, I get the same (on Leap 15.5). I never noticed because normally I do not call Gwenview from the command line, but start it by “clicking on” the name of an image file in some GUI application.

As it most probably being something in KDE, did you think about asking there? https://discuss.kde.org/

Might be related to this (Mon, 29 Jan 2024).

.
Maybe do the: STEPS TO REPRODUCE, to see if you get the same results.

If you compare what you found with what the OP posts, you see that it is the same (and it is the same as I see). And as there is no answer there, we are not one step further, except that we should watch that rather recent bugreport for what happens there.

No. They mean that definitions of these MIME types which are supported by Gwenview are not present on the system. Briefly looking at the Gwenview source, the only effect will be on the dialogue where you can filter by MIME types (missing MIME types will not be offered). It should not have any impact on opening these files. Dp you have any evidence that Gwenview fails to open such file?

Thank you for the clarification.

No, I don’t have any issues with opening any files. I would just like to turn off the warnings.

7

But is that really worth polluting the users output on each and every call of the tool? A bit exaggerated IMHO.

8

And you address it to me for what reason exactly?

9

Just to find out your idea about the logic/usefulness of what we see here.

But when you have no meaning about whatsoever, you can ignore it.

10

Not exactly.
In the Bug report, the person executed

gwenview --fullscreen <directory>

… the OP executed (no directory specified)

> gwenview   some-image.jpeg

… so the output is not exact (though the OP did not include ALL their output).

Anyway, the resulting output of the Bug had an additional line:

kf.config.core: Watching absolute paths is not supported

… which is also detailed in the Title of the Bug. And why I suggested that the OP execute as in the Bug report.
.
And yes, the Bug is not resolved and no progress has been made.
Why? Because it’s only days old (29 Jan 2024 :slight_smile: )
Not many [average, every day] bug reports get resolved that quick :slight_smile:
.
Also, it should be noted that, it’s been generalized, that the “Unresolved mime type” warnings are related to “there is no known preferred app to open it”, and not necessarily related to the executing app. Rumor has it that warning is coming from the system, not the app.

A basic search shows that this was already reported in june 2023…

I get the same results as in the bug report:

I’ve posted the question on the KDE forum: Unresolved mime type warnings - Help - KDE Discuss

The answer from the KDE forum helped me turn off the debugging messages by creating a qtlogging.ini file:

$ mkdir -p ~/.config/QtProject
$ vi ~/.config/QtProject/qtlogging.ini

Then add the lines:

[rules]
org.kde.kdegraphics.*=false
kf.i18n.kuit=false
