QML imports search order wrong

QML imports search order is: applicationDirPath(), $QML_IMPORT_PATH, QLibraryInfo::ImportsPath.

On Symbian platform, import path should be searched on all available drives in descending alphabetical order, from Y: to A:, and ending with the Z: drive. The search ends when the file/directory is found, or when every available drive has been unsuccessfully searched.

Import path searching on drives seems to be searched in wrong order, starting from Z:.
The attached debug prints show that QML Gallery application is on C:. The application imports Qt Components that are on E:, C: and Z:.
Qt Components on Z: are used, although the ones on E: should be used.
