TypeError: coercing to Unicode: need string or buffer, bool found

Hi,
when I try to save a SparseMatrixSimilarity object using the latest develop code in git, I get a TypeError.
Below is the complete output.
Note also the line: INFO:gensim.similarity.docsim:storing SimmatrixSparseMatrixSimilarity object to False and False.npy doesn't look very correct. (my SimmatrixSparseMatrixSimilarity class just extends SparseMatrixSimilarity and adds custom load/save.. HOLD ON, let me figure this out myself first. probably my own mistake :p )

this is a PEBKAC.
i was using custom save/load functions that didn't behave as they should
sorry for the noise.
