Hi and thanks for posting this. Even though I am a FreeBSD user, your posted 
problem (and subsequent solution) were similar-enough such that after upgrading 
'gdk-pixbuf-2.23.5_1' to 'gdk-pixbuf-2.23.5_3' (graphics/gdk-pixbuf in 
FreeBSD), 
my broken Pidgin 2.10.6 png files came back into view.  They exist in 
/usr/local/share/pixmaps/pidgin... just didn't load up right. :)

Nice!
Thanx,
Nick Zervas

I replied to this thread because I don't have the original png update thread 
around
anymore. I'm seeing this in terminal when playing pokerth:

libpng warning: Interlace handling should be turned on when using png_read_image

Seemed harmless though; I didn't see any graphics missing.

On that particular point, firefox uses its own copy of libpng because it
has patches for APNG.

png busted?

[joshua stein]

on a -current amd64 machine, i've noticed at least two packages
can't load png files with png-1.5.4.

pidgin 2.7.11p1 shows broken image icons for many icons in the user
list and conversation windows.  running it with its -d debug mode
shows the errors:

trying to open one of those png files in geeqie-1.0v0 shows a
similar broken image icon and spits out:

(geeqie:13400): GdkPixbuf-WARNING **: Bug! loader 'png' didn't set an error on 
failure

strangely, the same file can be viewed just fine in firefox, linked
against the same libpng.  similarly i downloaded a png file that
viewed fine in firefox and geeqie can't open it.
