todays d-u may break (some) gtk icons

[michaa7]

After todays d-u on 32 bit computer I have missing icons with gtk applications like thunar . reportbug (gtk) won't start anymore due to missing debian logo.

If you see this warning during d-u

(gtk-update-icon-cache-3.0:889): GdkPixbuf-WARNING **: Cannot open pixbuf loader module file '/usr/lib/i386-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache': Datei oder Verzeichnis nicht gefunden

This likely means that your installation is broken.
Try running the command
  gdk-pixbuf-query-loaders > /usr/lib/i386-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache
to make things work again for the time being.

it's to late as running the mentioned command will fail: No such command.

It seems to be an older bug which only triggers during update!


EDIT:
I have no clue how to fix it.

If you won't wait for this package being fixed install "libgdk-pixbuf2.0-dev" and run

gdk-pixbuf-query-loaders > /usr/lib/i386-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache

Thanks Melmaker

Hello michaa7,

you can find out which package contains any given file with apt-file  (needs # apt-file update",  e.g. with cron):

Code Select Expand

$ apt-file search gdk-pixbuf-query-loaders
libgdk-pixbuf2.0-0: /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders

This result is from an amd64 architecture. You will have to use a different path.

greetings
musca

Hi musca,

1) thanks
2) one better searches @ packages.debian.org as "apt-file update" is APITA
3) the problem here was that the non-dev package is broken. It should have updated the gtk icon cache during d-u without user interference. This is a known recurring bug.

- we should consider this as a long standing packaging bug - it would be interesting to know, which script call this sequence
and by the way, i'm affected too, did a d-u on my office LXQt VM

so installing the dev package should solve this, but i don't agree to see this as a proper solution

Neither do I. That's why I filed a bug report. Your invited to join it (= confirm the bug's persistence).

michaa7: i will, but first a little bit homework. You remember my first advice: install it - and musca ap-file search. looking at this output i think the executable should be in the regular and not in the dev package. A diff to stable or testing will help - and after that i think i should write a patch.

... looking at this output i think the executable should be in the regular and not in the dev package....

THAT sure as hell is right.

And that's why your advice "install gdk-pixbuf" didn't work immediately. I saw the dev packages. But it seemed insane to *need* a dev package for some gtk icons to work.

[melmarker]

it is insane

[michaa7]

Shit, you are right.
