    @qxoz: Nope, nothing has changed.
    @SGaist: Nope, I don't. Nothing has changed when I did so.

      Try to update the PATH of you run environment so that it also points to the folder where the mysql dlls are

          I faced this issue before. try to fix it as following:

          • put libmysql.dll in your application path (not in your project path in case you configured run from shadow build path)
          • put SQLDrivers folder in your application's path

                      Sorry my mistake, I forgot you use 12.04 (I'm using 13.04) just call:
                      [code]sudo apt-get install libqt4-sql-mysql[/code]

                          IIRC, you need to also install libmysqlclient-dev
