The assertion indicates that the index lock is not being held, but ParameterGuessingProposal is using the ASTProvider mechanism to access the AST and index, which ensures the index lock is held. Ideas about how this could be happening are welcome. (A reproducing testcase is also welcome, though I realize that's probably a long shot.)
