javascript Handler panic with rs.SetUservar

[julianfrank]

I tried the example provided

// JavaScript Object Macro Examples
! version = 2.0
> object setvar javascript
	// Example of how to get the current user's ID and set
	// variables for them.
	var uid = rs.CurrentUser();
	var name  = args[0];
	var value = args[1];
	rs.SetUservar(uid, name, value);
< object
+ javascript set * to *
- Set user variable <star1> to <star2>.<call>setvar <star1> <star2></call>

but it only ends in panic

I'll have to debug it and see if I'm doing something wrong with Otto, cuz most of that stack trace is in their code.
