occasionally when trying to reload particular feed as a livemark, we see cache expiration time of 0

looking at nsHttpChannel::UpdateExpirationTime(), could this be caused by mResponseHead->MustValidate() returning false, and so we call mCacheEntry->SetExpirationTime() with 0?

I'll try to make this happen in the debugger to figure out why the expiration time might be 0.

This is also occasionally seen on Mac OS X as well, also tested with the cnn rss feed.
