Comment (by vbraun):
I agree that it looks like
`sage.structure.unique_representation.CachedRepresentation.__classcall__.cache`
If I change the remove() callback to
{{{
import sys
print >> sys.stderr, 'removing', wr.key in
self.data.keys()
del self.data[wr.key]
print >> sys.stderr, 'finished removing'
}}}
then I get
{{{
...
removing True
finished removing
removing True
Exception KeyError: (((<class 'sage.categories.algebras.Algebras'>,
Callable function ring with arguments (x, y)), ()),) in <function remove
at 0x1acf758> ignored
removing True
finished removing
removing True
finished removing
...
}}}
So the weakvaluedict (self.dict) is in a bad state...
