My feed unavailable to Bloglines users

But it's not because my feed is broken

This is annoying. My blog feed is working fine. Works in Rojo (I set up a test account to see if all was OK). Works fine if you type the feed URL into a browser. But Bloglines (another testing account) says my feed is nowhere to be found. And yet they can find all my other feeds, which are hosted on the same blog provider. Until B/L can find this particular feed, I obviously can't put one of their buttons on my page. Are they always so unreliable, or is there some magical reason why this one RSS feed is invisible to them?

Did you created a feed or do you used a feed provided by a common blogging platform?
If yes which platform?

The blog that does not appear on Bloglines is hosted on blogsome.com/

However, a totally different blog (also on blogsome.com) does appear ok on Bloglines.

Both of the above blogs' feeds are ok if you just type the addresses straight into your browser.

And the one that has so far failed to appear on Bloglines seems to be easy for other online rss readers to find. My guess is that there is some peculiarity that is solely to do with bloglines. Logic says there is really no other explanation.
