> There is something strange in the fact that testing things with Python
2.7 (I also use Debian unstable, Python 2.7 has recently entered Sid) and
the same simplejson 2.2.0 version (provided by debian python-simplejson
DEB package) doesn't show these failures.

system and I see the reported failures.

The reason for this is because additionally the version of Decimal shipped
with Python 2.7 has a new `Decimal.from_float()` method that gets used
during decoding from JSON operations instead or raising the error reported
with Python 2.6 by the OP. This method can lose precision and neither we
nor simplejson can control that.
This seems to be an additional reason to keep using strings to encode
Decimal's
