Comment 5 for bug 779638

I can confirm the same behavior. My systray is set to 'all' as well, and the farthest left indicator icon is unclickable when there is 1 systray icon open. (doesn't matter which systray icon or indicator icon it is, it is always the farthest left indicator icon)
If I have 2 systray icons open, then the farthest left indicator icon seems to work intermittently.

felix, does changing the number of systray icons open change any behavior for you?

Note that if I have it set to 'all' but no systray icons open, everything is fine.

hopefully this helps to narrow down this bug!
