You are missing an "=" sign after key1. Confront with this example:

from cgi import parse_qsl

QS = "x=1&y=2&x=3&z=&y=4"
print parse_qsl(QS)
print parse_qsl(QS, keep_blank_values=True)

which gives

[('x', '1'), ('y', '2'), ('x', '3'), ('y', '4')]
[('x', '1'), ('y', '2'), ('x', '3'), ('z', ''), ('y', '4')]

Here the blank value "z=" is converted into "z=''".
