Might be a DLL mismatch. If you compiled your app with Qt 4.8.3, for example, it's best to use DLLs of the same version, build with the same compiler (MSVC and mingw are not binary compatible).

Qt obviously has binary compatibility promise, but it's - understandably - only kept one-way: you can run an older binary with newer DLLs, but not vice versa.
