Infinite loop when width is too small to display truncateText

[kaiw]

When the available width is less than the width of truncateText, the do-while loop spins infinitely because the width check will never succeed. In this case, I think that the only reasonably thing to do is to give up. The patch below works in my testing.

                 }
