For some reason I cannot load python2.6 from gdb:

This GDB was configured as "x86_64-apple-darwin"...Reading symbols for
shared libraries .. done

(gdb) run
Starting program:
/Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6
Reading symbols for shared libraries +. done

Program received signal SIGTRAP, Trace/breakpoint trap.
0x8fe01030 in __dyld__dyld_start ()
(gdb) The program is running.  Exit anyway? (y or n) y

This is the same as superuser.

I instead fell "back" to dtrace (``dapptrace -b 100m -U -p <pid>``,
which requires superuser privilegue, hence my note above).  dtrace is
a pretty decent tool to trace function calls etc. on the kernel level,
and ships with OS X 10.6.  I send the gzip'ed output attached to an
off-list mail, the full log is 4.8 MB even gzip'ed.  I found it by
first inspection useful to grep for ft2font.so and libfreetype.  Make
your own conclusions.  From what my naked eye can see, freetype itself
seems to be not the problem.  The last thing freetype appears to do is
to return from FT_GetSfnt_Name.
