External Applescripts stopped working?

[richls]

I have an Alfred workflow that opens an Applescript contained in a script file.  It used to work just fine.  As of today, it seems to have stopped working through Alfred - nothing at all happens when I run it.

 

This also happens with some scripts that I run from the Alfred command line.  I have "Run applescripts instead of opening" checked, but when I navigate to a script and open it, nothing happens.  Oddly, this happens only for some scripts, while others seem to work.  The scripts all work when I run them from Applescript Editor, or if I save them as applications and run the applications from Alfred.

 

The only change I've made in the last few days that might affect this is that I upgraded Mountain Lion from 10.8.4 to 10.8.5, and I upgraded to the latest MacBook Air firmware. 

 

Is anyone else experiencing this problem?

I've confirmed that this has nothing to do with the script - it happens even for a simple script I created that is nothing more than

 

tell application "Firefox"
    activate
end tell
 

This works when I run it from AppleScript Editor or save it as an application, but it does nothing when I run it in Alfred, whether through file navigation or through a "Launch Apps/Files" workflow action.
