The others were all hacking/security cons. Hackers on Planet Earth, DojoCon (small DC-area con), and ShmooCon, specifically. I think the hacking community, in general, is fairly well-known as being in the same state as the FOSS community when it comes to male:female ratios and commonality of misogyny. I suspect if I attended more "mainstream" tech events (Java developer conferences or MSDN stuff, for example) that those would have more women in attendance (closer to on-par with the percent graduating with CS degrees or working in the field, that is, about 1/4 of attendees being women) and fewer issues.
Actually, the only con I've attended where I can't say "one of the years I was there, $bad_thing happened" is the Debian one, DebConf. This was also the first year I attended, but I'm hoping that's a trend that will at least stick if I get a chance to go again.
