I have tried this on SuSE 8.1, same evo & libpng versions you have, and
I have no such problems.  Several things to note:

1) Evo itself isn't compiled against libpng.  It is, however, compiled
against libraries which are compiled against libpng (imlib,
gdk-pixbuf).  We're currently compiling against the SuSE 8.1 imlib
(1.9.10-474) and gdk-pixbuf (0.18.0-79).  It's possible one of those
libs is generating the error.

2) It's possible your libpng installation is somehow broken. rpm -V
libpng might shed some light.

3) I don't suppose you've been compiling things from scratch on this
machine? If you have e.g. an imlib you built yourself that isn't in
package management that is getting linked in, that might be causing the
problems.  ldd /opt/gnome/bin/evolution might shed some light.

4) Was this a clean install of SuSE 8.1, or an upgrade from an earlier
SuSE version?  If the latter, perhaps some older libraries survived the
upgrade?
