Assertion failure on hotshot.stats.load()

[Yang]

Note: I realize hotshot is obsoleted by cProfile, but 2.5 breaks
several packages I depend on. I'm using Python 2.4.3.

I'm getting an AssertionError on "assert not self._stack" when calling
hotshot.stats.load() on my app's hotshot profile. The app consistently
causes hotshot to generate such a problematic profile, but I have no
idea what's causing it. Anybody know what's wrong?

Here's the profile:

Thanks in advance for any help.
