Comment 4 for bug 144330

I can confirm this in Gutsy most recent update (I used the "Report a Problem" menu so details should be attached). Whether using Compiz or in Metacity, if I have Rhythmbox as the active window and I use the FN volume keys or the laptop's frontal volume hotkeys to change the volume,

NOTE: I'm not sure what this bug did in the past, but currently it only makes Rhythmbox (and any other applications I switch to) hang for about 20 seconds. When I test this in Compiz, the Rhythmbox window fades dark to indicate nonresponsiveness. Then after 20 seconds or so it returns to normal. As mentioned above, using sliders to change volume works fine. The FN volume keys also work fine AS LONG AS Rhythmbox is not the active window, or if I am switched to another desktop.

I'm running an Inspiron 1520. My device DB key is <8571d049b59a4f8a891c8a773a3b16e1>. I hope this info helps. It would make sense to me if it were an issue with GTK, but on the other hand I've only ever seen this happen with Rhythmbox.
