When I tried to edit this question, I got an error saying the title must be at least 15 characters.
How did this come to happen (given that it is a new question)?
Shouldn't the title written during posting also be 15 characters? Is there some text which is removed during posting which could cause this? Like tags? Maybe it's because trailing spaces are still allowed in the original post?
I bet that what happened is that the user originally wrote:
Run time error.
Which just happens to be 15 characters... with the period.
When you submit your question, Stack Exchange automatically strips out ending periods - which is why the current title is only 14 characters.
