Had a problem, found the cause - think it was a bug?

Bug... when leaving default blog name (ie My Lifecast), for some reason the blog type keeps defaulting to Blogger! I didn't realise why my tumblr posts were failing with the big old blogger error mesage until I noticed that blog type kept resetting to Blogger. As soon as I renamed the blog the 'Tumblr' blog type stuck in place and my posts work first time.
