Comment 109 for bug 36812

Yesterday I upgraded to maverick and today experienced layout switching bug. Not sure if it relates to the original xserver because I immediately installed patched version kindly provided by Oded Arbel.
However, here is how it looks like: at a random moment when I switch layout gnome-settings-daemon spikes to 100%, active layout is 'stuck' (i.e. it does no longer switch) and when I press and hold a key a random sequence of two characters is printed (chars from two installed layouts mapped to the same key). My second layout is cyrillic, so if I hold down "ф", printed sequence looks like "фaфффaaaaфaaaффaфaффффaaaa".
I haven't found any guaranteed way to trigger such a behavior, but is does happen several times a day at moments when I switch layouts actively (1-2 times a second).
Have anybody else faced something like this with the original xserver and/or patched version?
