png icons suddenly missing from kmenu and kicker

[unixj]

Hello, I'm not sure what I did but suddenly there are several icons missing in kmenu and kicker. In kmenu the space for the icon is blank and in kicker there is just the generic gear icon. I think they might all be png icons and they all still exist in /usr/share/icons.

This happened on 2 different machines- maybe after I ran emerge world.

Has anyone else had this problem?

[dbasetrinity]

have you tried

[unixj]

Sorry already tried that. I've also tried re-emerging the relevant applications (k3b, amarok and digikam) and their dependent packages, along with a bunch of other random packages like libpng and mime-types... Re-emerging kdebase-data, kdebase-kioslaves and kdemultimedia-kioslaves... And re-emerging kdelibs. The application icons are still missing in the kmenu and kicker. It's more than just those 3 applications I mentioned though, it seems like every png icon will not show up- like 50 applications.

One other data point is that digikam (or at least digikam) is completely broken. It gives the error:

Okay, I'm now experiencing this myself too. And in addition to that, I'm having problems emerging Gnome:

/usr/bin/gdk-pixbuf-csource --raw --build-list gnomecc_rounded_rect_frame
./text-selection-frame.png > gnomecc-rounded-rect-pixbuf.h
failed to load "./text-selection-frame.png": Couldn't recognize the image file format for file './text-selection-frame.png'
make[2]: *** [gnomecc-rounded-rect-pixbuf.h] Error 1

So, what's the problem? Some library dealing with pngs?

[unixj]

I'm glad I'm not alone! Maybe this will happen to other people as they emerge the mysterious package that caused this? I've submitted a bug report for digikam:

http://bugs.kde.org/show_bug.cgi?id=119424

Although I doubt this is specifically a problem with digikam.

I found a solution! It seems to be so, that GTK+ (gdk-pixbuf) uses a data file to decide what it should do with
files. This file is kept at /etc/gtk-2.0/gdk-pixbuf.loaders. It seems to have broken somehow.

Running the following command fixes it and returns all my precious icons

[unixj]

Doesn't work for me... My gdk-pixbuf.loaders file hasn't changed in a month and running gdk-pixbuf-query-loaders generates an identical file

[rhetoric]

That worked very well for me. I just installed a fresh system and then updated all installed packages and found the .png icons broken in the quick launch and kmenu. Immediately upon running this command, they were restored. Thanks!

Hey there,

same problem here with kde. It seems every png was gone. Even my Spalsh screen is empty.
At first i thought, that it was the libpng which was updated from 1.2.8 to 1.2.8-r1 a few days ago.
But a downgrade didn't work. revdep-rebuild neither.

I got a lot of this in my .xsession-errors:
libpng error: Invalid image width

Some KDE-Programms crashes.

I'm running an amd64 machine here.

So has anybody a hint where to search.

Greetings

Hallo again,

things are even worse...
I know recognized, that the image problem is not limited to pngs...
If i want to view jpegs inside of konqueror (which is completely iconless), the konqueror crashes.

Only som icons ar shown (form mozilla and eclipse for example). I assume, they are xpm's or something
like that.

Any hints out there.
At this moment i am recompiling qt...

Any help is appreciated.
Greetings
Don Martio

Sorry no idea. I was the original poster and I'm still having the problem. There's another thread about it here:

Ok everything back again.

I remerged qt and know everything is ok again.

All Icons and images are back.

Thanks at all

I finally figured this out, 4.5 months after the problem started <drumroll> apparently it's because I was using tcsh instead of bash. I chsh to bash and now the icons have reappeared. Hope this helps someone else.
