Seems like a pretty specific and rare special case that isn't worth expanding the code base to fix. That said I think this might work and not require any more code (needs more testing though):
Change
quickExpr = /^[^<]*(<(.|\s)+>)[^>]*$|^#([\w-]+)$/
to
quickExpr = /^[^<]*(<(.|\s)+>)[^>]*$|^#([\w-]*)$/
which is just changing + which requires at least one character to * which doesn't (this special case where input is "#").

Confirmed; However this is not documented in the API as a valid selector, however IS a regression in behaviour
exception thrown in 1.4.4rc1 http://jsfiddle.net/rwaldron/eHtAU/2/
passes with 1.2.6 http://jsfiddle.net/rwaldron/eHtAU/3/

Retargeting to future since this is not likely to actually affect anyone.

It's an error case...I guess it should return an empty object though.
