Steps to reproduce:

Test code: (test.c)
#include <gdk-pixbuf/gdk-pixbuf.h>
#include <stdio.h>

int main(int argc, char *argv[]) {
int files = argc-1;
int cur;

for (cur = 1; cur < argc; cur++) {
GdkPixbuf *pbuf;
GError *error = NULL;

printf("Trying to load '%s'...", argv[cur]);
pbuf = gdk_pixbuf_new_from_file(argv[cur], &error);
if (pbuf != NULL) {
puts("Success");
g_object_unref(pbuf);
}
if (error != NULL) {
printf("Error: %s\n", error->message);
g_error_free(error);
}
}

printf("Done loading %d files\n", files);
return 0;
}

gcc test.c $(pkg-config --libs --cflags gdk-pixbuf-2.0) -Wall -Wextra -O3

Except it's not built without png support, it's built with png support statically linked instead of as a module. I was troubleshooting this earlier on IRC and built the package with png support as a module and it made no difference.

I cannot reproduce with your example.

After I installed xfce4 the problem is fixed automaticlly. The environment before I installed xfce4 is
* new archlinux on VirtualBox
* xorg (all) xorg-xinit xorg-server xorg-server-utils
* virtualbox-guest-utils
* xterm
* xf86-video-vesa
* awesome

Are you the same guy from IRC that was having this issue? He was on VirtualBox as well and had installed the entire xorg group (which you should not do).

So it appears to be some missing dependency.

Maybe. I only report this issue on IRC and someone tell me to fire a bug report. That's all.
Comment by Doug Newgard (Scimmia) - Monday, 02 January 2017, 16:03 GMT
Not the same guy, then. We know at least 2 people have run into this. :(

Awesome upstream has pointed this out: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=801170

Could be the same issue.

Edit: someone on IRC just confirmed it. Missing dep on shared-mime-info.
Comment by Jan Alexander Steffens (heftig) - Monday, 02 January 2017, 19:48 GMT
Technically it's glib which consumes the mime info, and gdk-pixbuf just uses glib's type sniffing. But adding the dep to glib2 would create a circular dep.
