 That was a wash. :( Same result.

 Next I tried changing the various links to point to  libpng12. ldd
  showed that kate built with libpng12 and
libpng14, but  once again, no
  icons in the kate toolbars.

 Only kate is affected by this. No other app.

 I noticed every time I start kate that something  deletes the user's
  kateui.rc file, which would partially explain the
lack  of icons,
  although kate should revert to the default
kateui.rc  file.

 I suppose next I'll try deleting all libpng14 files.

 Listening for ideas....  Did you try setting PNG_CFLAGS / PNG_LIBS or using sed,
as
 the message
 I quoted suggests ? I think sed would definitely prevent
 kate from
 using libpng14 (or libpng12 if you want to force the use of
 libpng14).
 But I'm not sure the libpng versions are really the
 problem, since you
 said that without using kdesu there is no issue. Did you
 try running
 Kate both with commandline sudo, su and su - ? If the
 results are not
 the same, there are problems with environment variables.

 I don't see any such flags such as PNG_CFLAGS / PNG_LIBS. I also never have seen a
separate build script for kate. The only place to set build flags is when building
kdebase.

 I doubt the problem is related to kdesu ore nvironment variables. As I wrote previously,
I see the problem only with kate and not with any other app started through kdesu.

 As I wrote previously, same problem with running from the command line. That is where I
see the error messages about the two different libpng versions.

 I'm going to rebuild all packages with only one version of libpng installed. That
will eliminate that variable as a cause. That is not a smooth solution because many
distros install both versions of libpng. Trinity will have to address this problem sooner
or later.

I have no problems with kate under kdesu. I've compiled kde3 on slackware-13.1 and
-current using default slackware's libpng.
Did you recompile qt-3 before building kde? What were your configure options? I used  qt3
slackbuild from slackware12.2 and changed "-qt-libpng" to
"-system-libpng".
Take a look at "KDE 3.5.10 for slackware-13.1" thread on linuxquesions.org to
check which patches i used.
