Description

See: http://lists.freedesktop.org/archives/xcb/2013-October/008689.html

To quote from that mail (more details are in there):

First, the summary if you don't want to read the whole story: It looks like every structure having a fixed size field after a variadic field/list is broken! Most other extensions are not affected as they've the variadic stuff at the end of a structure - not intermixed with fixed size fields.

[...]

This struct has a
- fixed size field (nameLength)
- variadic list (name)
- fixed size field (valueLength)
- variadic list (value).

Now, look at the generated structure:
typedef struct xcb_xkb_property_t {
    uint16_t nameLength;
    uint16_t valueLength; <-- doesn't belong here
} xcb_xkb_property_t;
