kartiksh, that can happen with Google as well, but it required a visible link to your pages that are protected by robots.txt

In this case the page will be listed on the serp, but will use link anchor as the title on the results page.

Are you sure there are no pages linking to your excluded pages, even log files that may be spiderable?
