bug: citations in figure floats

[Chris Eliasmith]

Hi,

I didn't find this as a bug in the help section, so I
thought I should mention it. Whenever I include a citation
(M-i i) in a figure float, I get the following errors
on compile (at the end of the float):
Illegal parameter number in definition of \reserved@a
<end of float text> You meant to type ## instead of #, right? Or
maybe you forgot a } somewhere earlier? I'm going to assume you meant ##.

I'm using 1.1.5fix1 on Win32.

Thanks, Chris.

ps Keep up the awesome work!
