Updated the mysql-driver for qt4.
The MySQL driver which is available in extras-devel is outdated and built for 4.6.2 afair, so I updated that package and here you are:

Upgrading that package with mine will make it work!

Tip:
Don't forget to uncheck checking the connection in mythfrontend's setup.

Only problem that has left is that it says that the time/timezone settings on my phone don't match with the one on the backend.
Try to install and give me some feedback
