Comment(by davidloeffler):
The vast majority of the stack frames are saved by the coercion model for
use in its introspection mechanism. Adding the line
{{{
get_coercion_model().exception_stack()
}}}
at the end of {{{sage/all.py}}} kills all but 9 of the 26 stack frames
listed above. Of the remaining 9, 8 are to do with IPython. The other one
is some silly generator in the combinatorics module that is there to
compute factorials; I don't know why they don't call the general-purpose
factorial function.
