[xmonad] Can avoidStruts stop working?

[Tuncer Ayaz]

Does anybody else run XMonad on Arch Linux AMD64 (non-testing)? Since
about a week (and a half) ago something seems to have caused
avoidStruts to be ignored, because xmobar is covered by any window I
open. I've tried unsuccessfully with my full config and the recently
suggested new sample config here on the list[1]. Any idea what's
happening? It's possibly an operator issue, but I don't know how to
debug it.
