BUG: Something kills evaluation of 0 in JS

Everything is normal until I load a new xml.
Before I load the xml I try to wipe the environment
For one action I'm checking the x of a plugin but it's NaN
ok. I set my x to a known value 77,
then I check it again

krpano.call("if(plugin[scene1129].x GE 0,trace(hi)))");
krpano.call("if(plugin[scene1129].x LE 0,trace(hi)))");

Neither work even though x is 77.
And this affects ALL evaluations against 0, not just this plugin.
So common functions of previous scene where it uses GE 0 are now broken.

also using 0 no longer works.. set(i,0);
Using 1 instead, and everything is normal. For the initial xml load things are normal

I tracked this down to the use of vars in loadpano or loadscene
HTML5 ONLY problem

loadscene(get(scene[0].name),null,MERGE);
works
loadscene(get(scene[0].name),wtf=whoknows,MERGE);

suddenly breaks the use of 0

krpano.call("if(plugin[hide].x GE 0,trace(hi)))");

xml used...
