I know nothing of inspect, but this certainly look like a bug (see below).

[Here is the output (from 2.2) you forgot to include'-):]
args: []
Traceback (most recent call last):
File "<stdin>", line 9, in ?
File "C:\Python22\lib\inspect.py", line 629, in getargvalues
args, varargs, varkw = getargs(frame.f_code)
File "C:\Python22\lib\inspect.py", line 592, in getargs
remain[-1] = remain[-1] - 1
IndexError: list index out of range
Error happens on second iteration. Getargs seems to be trying to index
into an empty list, which it either should not do or should wrap with
try-except.
If the same happens in 2.4, I would probably report it after looking a bit
at the inspect code and after adding a debug print before the getargvalues
call to see if the second record values looks as sane as the first set. If
you want a fix in 2.3.5, coming January, a patch would more likely get
action than just a bug report.
