    Resolution: Done

    P2: Important 
- 
    Qt Creator 2.6.0-rc
- 
    None
- 
    Ubuntu 11.04 32bit, Ubuntu 11.04 64bit
Steps to reproduce:
- Open Tools->Options->Build & Run->Qt Versions
- add a new Qt Version by clicking 'Add...' and specifying the path to qmake
- push 'Apply' several times
Expected behaviour:
- Qt version is added once
Current behaviour:
- Qt version is added multiple times (at least inside the options dialog - inside the Projects view I still have this newly added version only once)
