[issue2606] trace module crashes due to using wrong sort idiom

[Mark Summerfield]

New submission from Mark Summerfield <mark at qtrac.eu>:

In Py30a4's trace.py there is this:

    calls = self.calledfuncs.keys()
    calls.sort()

which causes:
    AttributeError: 'dict_keys' object has no attribute 'sort'

There are two other occurrences of this idiom in trace.py (just search
for ".sort"). I guess they should be easy to fix.
