predicated gem error

Hi, and congrats, predicated just busted rubygems, twice!:

I had to fix the date manually. Actually it seems like a bug in rubygems
that a bad date in one spec could bring the whole system down.

The date spec thing is a rubygems bug. It seems to happen when the releaser (me) generates a gem with RubyGems 1.8.2, and only shows up on some people's systems when they install said gem (i.e. I didn't catch it cause it worked for me). I'll do a new one asap and let you know when it's pushed.

What was the second bug? Or was that just the same bug twice?

It was the same bug twice, with 0.2.3 and 0.2.4 a few minutes later.
Thanks!

OK, please try gem update again -- 0.2.6 might be money. (I'm releasing 3 different gems right now so I may have gotten a bit confused; if so, let me know and I'll try again.)

BTW the issue is actually with Ruby itself -- building the gem with 1.9.2p180 makes a metadata field with a different date format than building the gem with 1.9.2p0. And that new format is unreadable by older versions of Ruby. I think it's that they added fractional seconds to the time, and the poor old date parser breaks when it hits ".0000000".
