Hi satyr,
thanks for taking the time to look over this. Your snippet and my
script both work fine with most GM scripts. The problem arises when
the GM menu command invoked from Ubiquity uses some GM_* API function.
In order to reproduce it with your snippet, you have to create a
one-line Greasemonkey script like
GM_registerMenuCommand('foo', function(){ GM_setValue('bar', 42) });
and ensure you place the script *first* in the script list (this is
because your snippet executes the first menu command it encounters; if
you have more than one, you have to place the GM script above in the
list to ensure the menu command get registered first as well.)
If you do that, you'll see in the error console:
Error: Greasemonkey access violation: unsafeWindow cannot call GM_setValue.
As I said in the GM thread, I modified the GM extension to show more
in depth information about the error. What I'm getting in this case
is:
Error:
Greasemonkey access violation: unsafeWindow cannot call GM_setValue from

Greasemonkey then sees that the first call comes from a file: url
which doesn't belong to Greasemonkey, and disallows execution. I've
already talked the GM guys about this, but I am curious about why
Ubiquity scripts are "file:" urls and not "chrome:"
