Error: Invalid arguments to GM_util.hitch() when trying to use setTimeOut() #1552

FF 12.0
GS 0.9.19

Rolling back to 0.9.18 fixes the issue.

When a script is using setTimeOut in the Error Console I see " Error: Invalid arguments to GM_util.hitch(). "

yes, I got the same problem. the same code worked just fine yesterday, and today it doesn't work anymore. I checked the add-ons in FF, it just updated the GM to 0.9.19, and it doesn't work anymore!
btw, the setInterval() works just like before.

Note: This only happens when using a string as first parameter to setTimeout, e.g.

setTimeout("alert(1)", 0);

I had it happening with either of these cases, so maybe when it parses a string?

} else {
setTimeout(function(){window.location.href = 'page.php?id=2'}, 4000);

I didn't think passing a string to setTimeout ever worked. Isn't that one of the "Greasemonkey pitfalls"?

There's two separate issues

1) If you pass a string to setTimeout it fails with "Invalid arguments to GM_util.hitch()". This used to work in 0.9.18.
2) If you use a delay of ~> 2 seconds setTimeout fails silently.

setTimeout(function() { alert('foo1'); }, 1000);  //This works
setTimeout(function() { alert('foo2'); }, 5000);  //This fails silently
setTimeout("alert('foo3')", 2000);  //This fails with GM_util error
