Qt4 jpeg support broken

Well I just have written aprogram in Qt4 and in Feisty it works all good, bu t problems with Null image reading jpeg files only occured in Windows XP so I don't think it is a problem with Ubuntu

Well, I switched from Qt4 to openCV for the image handling now, so I can't check if an updated package exists, but I have a stock install with all qt4 packages installed and it didn't work on my laptop. It was a fresh install when feisty was released.
this is weird, because I did not mess with the qt configuration, so I'm wondering why it's broken in my system. But if it works for others, thats fine :)

Hi, I think it works in Feisty for Me because I used APT to install the packages, On XP though I used downloaded version from Trolltech and it's standard configuration does not include jpeg support, and the download version for linux is configured in that way I think

I used apt too, of course

I can confirm this problem:

$ python
Python 2.5.1 (r251:54863, May 2 2007, 16:56:35)
[GCC 4.1.2 (Ubuntu 4.1.2-0ubuntu4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from PyQt4 import QtCore, QtGui
>>> [str(x) for x in QtGui.QImageReader.supportedImageFormats()]
['bmp', 'pbm', 'png', 'pgm', 'ppm', 'xbm', 'xpm']
>>>

No JPEG support visible, as well as documentation mentions that JPEG support
is available, and the file
/usr/lib/qt4/plugins/imageformats/libqjpeg.so
exists.

No further idea what might be the reason.

For qt3, it works:

$ python
Python 2.5.1 (r251:54863, May 2 2007, 16:56:35)
[GCC 4.1.2 (Ubuntu 4.1.2-0ubuntu4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from qt import *
>>> QImageIO.inputFormats()
['BMP', 'GIF', 'JPEG', 'MNG', 'PBM', 'PGM', 'PNG', 'PPM', 'XBM', 'XPM']

Thanks for the confirmation, I thought I'm getting crazy and seeing non existing bugs ;)

works for me using latest Qt 4.4.x
