Maurice,
We deployed the application with the qjpeg plugin (we know it works because
other jpg's work fine).
We use the same piece of code that you gave as an example in our
application. The qfile::readAll() was just to see what exactly was causing
the problem.
The qDebug output of readAll() is "ÿØÿà . We also still have like 80MB ram
free on the device so I doubt it's a memory related problem.
Regards
Matthias
