Bug 20933

I'm trying to learn XCB via xpyb-1.0, and I noticed what I think is a bug.

I'm trying to get the value of the _NET_SUPPORTED property on the root window.  According to "xprop -root | grep ^_NET_SUPPORTED | cut -d= -f2 | wc -w", there are 76 atoms in my _NET_SUPPORTED.

I have attached a script to get that same list of atoms, but it looks like the (auto-generated) value() method on GetPropertyReply is returning 76 CARD8 values instead of 76 CARD32 values.

I am invoking GetProperty like this:

=== SNIP ===
# Get the _NET_SUPPORTED property
voidcookie = conn.core.GetProperty(
    False,              # delete
    root_window,        # window
    XA_NET_SUPPORTED,   # property
    XA_ATOM,            # type
    0,                  # long_offset
    65535)              # long_length
reply = voidcookie.reply()
=== SNIP ===

The values I get back look like this:

=== SNIP ===
reply.format = 32
reply.type = 1 ('PRIMARY')
reply.bytes_after = 0
reply.value_len = 76
len(reply.value) = 76
reply.value = [74, 1, 0, 0, 126, 1, 0, 0, 36, 1, 0, 0, 79, 1, 0, 0, 80, 1, 0, 0, 81, 1, 0, 0, 35, 1, 0, 0, 130, 1, 0, 0, 89, 1, 0, 0, 128, 1, 0, 0, 129, 1, 0, 0, 91, 1, 0, 0, 131, 1, 0, 0, 132, 1, 0, 0, 43, 1, 0, 0, 90, 1, 0, 0, 42, 1, 0, 0, 137, 1, 0, 0, 40, 1, 0, 0]
=== SNIP ===

Am I doing something wrong?
