The attached XML expt crashes the Server in a recent nightly.  
Not an urgent problem but would be nice to fix.

Thanks, Mark. I’ve confirmed that your experiment crashes the server in 0.4.4, too. I’ll try to get this fixed soon.

Hi Mark,

The crash is being triggered by an error in your experiment: You set the name of the juice channel variable to “reward”, but there’s no variable by that name. You can avoid the crash by using the name of an actual variable (in this case, “juice”).

Clearly, the fake monkey plugin needs to do better error checking. I’ll open a bug report and get this fixed.

Thanks,  
Chris
