Alignment On All Galleries Page

This may be related to the themes I use, but on the main gallery page, the alignment is very screwed up unless ALL of the galleries have titles that use the same number of lines, be it one, two, or three. I'm assuming that it's using some sort of "float left" in css. (I don't know much about css, but I DO know that.)

Anyway, is this an issue in Media Gallery, or should I be messing around with the theme? If all of the blocks were the same height, it wouldn't be an issue, I suspect.
