Development branch "half works" on 64 bit Arch

Sorry for the vague description. This may be related to bug #401360, but I'm not sure.

I built a number of different revisions of musca from bzr and all of them have the same problem (r-266, 265, 264, 254, 240).

What's working:

It starts, it will split and remove windows, and the various dmenu launchers will start up.

What's not working:

None of the menus do anything (no musca commands function and no programs will launch). It ignores local configuration files and does not work with the defaults. It must be forced closed.

This is part of the console output after closed. Hopefully I wrote everything down correctly:

musca.c 3073 quiz_window musca unknown ignore focus unknown normal 0 0
musca.c 3079 createnotify musca
fatal error: request code=2, error code=10
X Error of failed request: BadAccess (attempt to access private resource denied)
    Major opcode of failed request: 2 (X_ChangeWindow_Attributes)
    Serial number of failed request: 72
    Current serial number in output stream: 74

It goes on a bit with the quiz_window stuff.

I'm on 64 bit Arch up to date with testing. The stable branch does work.
