Some of my favourite ones from trying to learn this new system include:

• invalid argument

Uh... I just typed in a magic incantation that takes up two lines on this text thing.

Which. Fucking. One!?

• no such file or directory

The final three words above apply here too. I got this one because a file I downloaded that was supposed to do something had ...insert long string of technobabble from SO that included the word shahbang, I swear! It took him over ten minutes to find whatever all the treknobabble he uttered meant and then half a second to fix.

So it's not even fear that's at issue. It's blank incomprehension when the error message is about as useful as those dummy lights in '80s-era cars that just said "ENGINE".
