Strange failure querying hotends while in progress

[astrobokonon]

Not sure if this is just a "busy" sort of signal from the ultimaker API or something, but I am seeing more failures along these lines:

Looking at the lines in question

Ultimonitor/ultimonitor/printer.py

Lines 232 to 238 in 14afe43

	bedtemp = api.queryChecker(printerip, "printer/bed/temperature")
	if bedtemp != {}:
	ext1temps = headinfo['extruders'][0]['hotend']['temperature']
	ext2temps = headinfo['extruders'][1]['hotend']['temperature']
	else:
	ext1temps = ""

I can just wrap them in a try...except block and see what comes out after that. Has happened once a day for the last 2-3 days now.

A better fix it to adjust the api helper file to account for this sort of thing, but I'm curious if more stuff downstream will fail so I'm going to try this.
