Interpreting python profiler results

I'm working on a piece of software that uses PyQt and PyOpenGL for
drawing acceleration. While profiling it to find opportunities to speed
things up, I got this from the profiler:
ncalls tottime percall cumtime percall filename:lineno(function)

....more.....
I assume ":0(getattr)" means a getattr function in either PyQt or
PyOpenGL. I grepped the sources of both looking for getattr, and it
doesn't appear in PyQt but appears frequently in PyOpenGL. Does anybody
know if I am correct in my conclusion that most of the program's time
is being spent in some getattr function in PyOpenGL?
Thanks
