trouble with libpng

[johan30 <johan30easynet.be@johan.apt-get.be>]

hi,
I think there is a bug with the last update this morning concerning libpng : 
when opening kmail :  (i work with potato, kernel 2.4.3)

libpng warning: Application was compiled with png.h from libpng-1.2.1
libpng warning: Application  is running with png.c from libpng-1.0.12
libpng error: Incompatible libpng version in application and library

Thx,
Johan
