Variables on the heap (global) are initialized to NIL;
but variables on the stack (local) are not initialized, 
they usually contain random garbage from who-knows-what.


That is why you get the:
   assertion `error == NULL || *error == NULL' failed

from the local "error" but not the global.


Try this...

  function getImage(loader:PGdkPixbufLoader; var s:string):boolean;
  var
    error : pgerror;
  begin
    error:=nil; // <-- ADD THIS LINE !!!
    result := gdk_pixbuf_loader_write(loader,@(s[1]),length(s),@error);
  end;//getImage()



Hope this helps, 

 - Jeff
