perhaps your gd package isn't compiled with png support? looking at
the source for libgd, it seems to have png support optional.

perhaps recompiling png will help. another option that works for me
in some cases is change the type from png to gif, sometimes that is
faster, though gif is generally a bad format to use(legal reasons mostly)

curious why you upgraded? I am running MRTG 2.9.17 with 0 problems
on multiple systems.
