After upgrading, I am seeing " " before the "As read" "As unread" "As flagged" and "As unflagged" entried on the right-click menu on the mail list view. I have attached a screenshot for review. Having run 0.9.0, I do not recall seeing the same issue...but I also was not looking for the issue, so it may have been there. My system was upgraded from 0.7.1 or 0.7.2 into 0.9.0 and then 0.9.1.
Two other items. First, I am seeing the same issue with each of the installed skins, so it looks to be outside of the skin arena. Second, it is displaying the same issue across Firefox, Internet Explorer, Konqueror and Midori (under Linux and Windows, as available).
Any reply with a resolution - even a manual fix, would be of great assistance. Thank you.
