Comment 32 for bug 625793

As I've reported in bug #636619

It happens for me too. It's still there, I've just checked. It's triggered by switching layout. After that, it goes crazy and layouts are switched cycling between my previously configured ones rapidly. Scroll lock led flashes as well (it's configured to show the non-primary layout). I can't even type since pressing the same key generates random character based on the fact which layout was active at the moment when I pressed the key. xev reports things like this without stopping (even without toucing the keyboard or the mouse after I managed to launch xev in a terminal window):

My system was upgraded from the previous version of Ubuntu (lucid lynx) I am wondering if it can cause the problem and it works with a 'clean' install (ie: new home directory with gnome/etc settings created by the current development version of ubuntu). I have four layouts configured, one of them (USA) is the primary, the others are configured to be signaled by the scoll lock led, and I switch layouts by key "scroll lock".
