Sometimes when I switch layout using either Alt+Shift or Ctrl+Shift the Alt key is not recognized as being released thus if I press e.g. F a File menu opens up. Last time that happend I lost all data I filled into a text form on a webpage because I pressed the Home key while typing and Firefox suddenly went to my home page! Moreoever, it still remains unreleased after hundreds of keypresses like if I'm holding it! Same goes for the Shift key.

I would rather file a bug at Launchpad if I could but I have no clue what fucking package name should I type in the ubuntu-bug command!

Have anyone else had this issue? Can you suggest a solution or maybe another place to report this bug?
