Public bug reported:
Binary package hint: python-launchpad-bugs
In the apport crash digger I do some set operations with BugList
results, and I just disbelievingly observed that one set grows like
this:
set([94694, 103275, 111139]) + set([94694, 103275, 111139]) ==
set([103275, 111139, 111139, 94694, 103275, 94694])
and so on, yielding an endlessly growing set with duplicates of the
original three bug numbers.
This is because BugList returns a set of strings, not a set of ints, and
apparently set collapsing uses object identity instead of object
equivalence. So, for ints, 1 is 1, but for strings, "1" is not "1".
I worked around this in apport now by converting the set of strings into
a set of ints. But this could bite other users, too, so I recommend to
return a set of integers right away.
