I've seen this error too on someone else's machine. Are you using the 
kmplayer tarball package or did you check it out from Subversion too?

I haven't been able to understand how exactly this bug came to be. My 
initial thoughts were that the use of KDE 3.4's admin together with a KDE 
3.5 causes -fvisibility=hidden to be used when KDE_EXPORT is not defined. 
But kmplayer does some #ifdef trickery to get the export back on.
