Since I am one of the moderators for Drupal Answers, I get notifications for every question asked on the meta site. Some minutes ago, I got two notifications for the same question.
I have checked, and there aren't two copies of the same question, nor does the question has an answer.
There isn't a deleted question with that title too.
Is it a bug, or is there an explanation for this?
I think it happened before, but I didn't ask a question because it was the first and I thought it was an hic-up.
This doesn't happen in the page showing all the notifications per questions, answers, and comments I get.
If this depends from the browser, I am using Google Chrome 26.0.1410.65 running on OS X 10.8.3. The revision shown for the site is 2013.4.19.658.
