As Skittles has pointed out, you should weed out typos with impunity in the main namespace, but there are other namespaces where typos should be cleared up, importantly including:
 * File:
 * Tardis:
 * Help:
 * Category:

As a very general rule of thumb, if the namespace number is even and less than 100 (the namespace page gives you numbers), go ahead and correct the typo. If the namespace is odd never correct the typo, and never point it out, unless, again, the typo makes the meaning of the sentence genuinely unclear.

[What's up with the even/odd business? Even-numbered namespaces are usually reserved for the "meat" of a particular namespace. It's where you'll find the actual pictures, the actual articles, the actual categories. Odd-numbered namespaces are what are called "meta" namespaces. They're "talk" pages used to "talk about" the content on the (talk namespace number - 1). So, if you're at unlucky ns:13 (aka Help talk), that's the talk namespace for ns:12 (aka Help).]
