(If we know, maybe we can go back to some stable version or something till this is fixed. Unity is crashing some 5-10 times pr day ATM - for everyone in our office! Both Mac and PC, different projects…)

You might have missed it, but Unity released both version 4.6 and the public beta of 5.x in November - two long-anticipated releases that caused a lot of additional traffic of all things Unity-related.

Try adding “Unity Release” or just “Unity” search terms to your trends graph and you’ll see they have exactly the same spikes as “Unity Bugs”…
