--- Short description of error ---

The description of IntProperty says:

"... min=-sys.maxint, max=sys.maxint, soft_min=-sys.maxint, soft_max=sys.maxint, ..."

Here, sys.maxint not existing in Python3 can be substituted with sys.maxsize. However, IntProperty actually uses INT_MIN and INT_MAX for the default range, and sys.maxsize is not same as INT_MAX.

On Ubuntu (64bit or 32bit),

sys.maxsize = 9223372036854775807 or 2147483647
INT_MAX = 2147483647
LONG_MAX = 9223372036854775807L or 2147483647L
LLONG_MAX = 9223372036854775807LL

So the description is apparently incorrect.
