SupportedImageFormats in Release and Debug mode

Hi,

I have configured Qt with:

configure -qt platform win32-msvc2008 -qt-libpng -qt-libtiff -qt-libjpeg -qt-no-webkit

I am noticing a strange behavior:confused:. When I run the code in debug mode,
qDebug() << QImageReader::supportedImageFormats(); show that following image formats are supported

bmp
gif
ico
jpeg
mng
pbm
pgm
png
ppm
svg
tif
tiff
xbm
xpm

However, when I run the same code in release mode only following image formats are supported

bmp
pbm
pgm
png
ppm
xbm
xpm

Why is it behaving like that??? :confused: I certianly need some help here!! This image formats plugin are making my life hell!!
