OS X 10.8.5
Alfred v2.0.8 (212)
I use the Dvorak keyboard layout.
Alfred's preferences show that my clipboard viewer hotkey is ⌥⌘C, the default. If I press these keys, nothing happens. If, however, I press ⌥⌘J, the clipboard viewer opens. This isn't completely bizarre, as Dvorak's J is located where QWERTY's C is. This leads me to believe that Alfred simply ignores the user's keyboard layout with regards to hotkeys, using QWERTY for everyone.
The issue is easily replicated. Any time I press ⌥⌘C absolutely nothing will happen; any time I press ⌥⌘J Alfred's clipboard viewer will open.
• The issue occurs both on my Macbook Pro's using its built-in keyboard and on iMac using an Apple wireless keyboard.
• OS X does have a "Dvorak - QWERTY ⌘" layout that uses QWERTY for any key combination involving ⌘ but standard Dvorak for typing, which would cause this behavior if it were the current keyboard layout. I've verified that I am not using this layout, and that ⌘C for copy works as expected.
• The computer has been in the Dvorak layout since boot, so switching between keyboard layouts while Alfred is running is not the issue.
• Closing and restarting Alfred causes no change in behavior.
• Switching to QWERTY and back while Alfred is running causes no change in behavior.
Let me know if there's anything else you need from me in order to replicate the bug.
