Version 0.9.95 fails to find known key in the following example:
-------------------------
i1 : L = QQ[x]
o1 = L
o1 : PolynomialRing
i2 : keys L
o2 = {(lift, L, L), 0, 1, generatorSymbols, generatorExpressions, ...
o2 : List
i3 : L.generatorSymbols
stdio:3:2:(1):[0]: key not found in hash table
i4 :

Version 0.9.2 works OK.
