This bug was originally marked as duplicate of bug 157913, that is already resolved. This bug is still valid, so this seems to be another bug, but it might be related.

This is most probably a problem with the patches from bug #206233. There blob.free() is called without checking, that there was actually a result (aka the result was not null). A fix is attached to that bug.

Actually duplicate is not quite correct, but is the nearest match to the truth as #206233 was reopened to clean up the collateral damage.
