If Julien was angry about the unsportsmanlike conduct penalty he had a legitimate beef. I don't think the Bruins were too happy either with the snow shower on Rask, considering the same play earlier in in these playoffs resulted in a penalty. They only ended up calling it when Krug responded, and even then, they called Krug as well.
Consistency shouldn't be too much to ask for, and that's the biggest problem I have with the officiating. If Price gets bumped in Round 1 vs. Tampa and they call back the goal, Rask getting sat on in Round 2 vs. Montreal should produce the same result. If a snow shower in Round 1 means a 2-minute unsportsmanlike, call it in Round 2. Isn't there someone in charge of these officials to make sure they're all on the same page?
