Ah. Makes sense.

Well, found a workaround. Not sure if this one is a bug or a feature 
(is a feature to me)

\title{some \type{\thing\{and\}}}

However, things get real weird.

\title{\type{$\Pr\{A\}$}}

gives me

<argument> ...tofoneargument {\type {$\Pr \{A\}$}}

l.69 \title{\type{$\Pr\{A\}$}}

which I think is the currect behaviour.

There is really no need to change anything. I am happy with "Do not 
use \type inside argument. The unexpected can happen."
