[Rivet] issue with mkhtml complaining about ReadError

[Andy Buckley]

Probably loading *something* with a matching name. The line being 
complained about *does* look like part of a YODA file... or maybe a .dat 
file that accidentally got named .yoda.

I'd like to know the answer -- could you try adding a "print infile" 
line to rivet-cmphistos just above the "analysisobjects = 
yoda.read(infile, ..." line on line ~110, and run again without the 
double-colon path forcing?

Thanks (and glad we've got a workaround),
Andy
