If Qt was built without FontConfig support, and the DejaVu Sans font is used, text may wrap around itself. This seems to only happen when a capital 'U' is followed by certain other capital letters, like 'R', 'K', 'P' or 'T'. For instance, The word "URLs" used in qtconfig gets wrapped, and the 'R' and any following characters start to the left of the 'U'.

A capital 'U' followed by 'L', 'M', 'X' or 'A' does not result in wrapping.

The problem has been reported to also occur with Bitstream Vera fonts.

This is a regression from Qt 4.3.
