Having checked this out in greater detail, it does appear that Kovid incrementally updates the source between binary releases.
The related issue is that the save search code won't run:
search_query_parser.py", line 42, in force_unicode
AttributeError: 'QString' object has no attribute 'decode'
FYI, as a temporary fix, I just forced x to be unicode "x = unicode(x)" at the point above, and the save search code works.
