I am fermenting my second all-grain batch; a brown SG 1.046; and it is day 13 since it started, and it makes a bubble every minute and a half. This seems like a long time; do I have an infection?

It's probably just off gassing CO2. One bubble every minute and a half isn't an indicator of much activity. Also, watching the bubbles isn't a great indicator if the beer is done. Take a gravity reading. Taste the sample. Does it smell and taste right?

13 day ferment is not unheard of... depending on a number of variables. That's why I don't like recipes that tell you do do things after a certain number of days... Like if the beer isn't ready to bottle on day X, don't do it!

The gravity is 1.012, and the taste is fine.
There is a big cap of yeast on top of the beer. I don't usually see that, though this is the first time I have used London Ale yeast (WLP 013).
I will probably bottle it today, and we'll see!

If it is bubbling that slowly then your beer is done and it is most likely CO2 outgassing from the fermenter. Have no worries, package up your beer and enjoy!

+1 on degassing. A temperature change (ie, beer getting warmer) will drive gas out and cause slow bubbling.
Check the gravity. Also, a fallen krausen will also indicate that it's pretty much done with primary fermentation and is now only processing the byproducts to clean up after itself.

beer bong the whole damn thing. if it tastes good, it's done. if it's too sweet, you shoulda waited.

Let it keep going... Do NOT bottle it too soon.
