Subject line is replaced by dots upon saving drafts or templates

I create a new blank message, type something into the subject field, save, and close the window. My drafts folder displays the new message, but instead of my subject line there are three dots. When I open the draft again, the subject line indeed consists of three dots. Replacing the dots again by some text does not solve the problem, after saving it will still have three dots. Thus, I cannot save subject lines in drafts. The same for templates. What's going wrong here?
