I've attached a document containing the terminal output and the qsynth console 
output when lauching qsynth with the following commands:

$ export DYLD_PRINT_LIBRARIES=1
$ open qsynth.app

I don't have access to any other mac.

Your console output looks normal, except for the line that says "Failed to load 
the soundfont". Anyway, there is not much information there to debug your 
problem, but I have some suspects: 

* your system is loading some libraries from somewhere instead of the 
frameworks included in the bundle. To debug this, you can execute the following 
commands in a terminal window and send me the output from the terminal and from 
qsynth messages window. There shouldn't be any referenced libraries except Mac 
OSX system ones.

$ export DYLD_PRINT_LIBRARIES=1
$ export DYLD_PRINT_LIBRARIES_POST_LAUNCH=1
$ open qsynth.app

* there is something in fluidsynth-SVN code that fails when loading soundfonts 
in your machine. To test this hypothesis, download fluidsynth from SVN (for 
instance:  http://fluidsynth.svn.sourceforge.net/viewvc/fluidsynth/?view=tar ) 
and compile it in the same computer. Does it load soundfonts? 

Lets try that first, before using instruments/dtrace utilities to dig deeper.

Pedro
