Yes I know, I just don't know where I do GUI stuff.

Does KProcIO make some xlib calls? Because other that that I only use
QImage, QByteArray, KTempFile, QString, QStringList, QFile, QFileInfo
and QDataStream.

Why? From the Qt3 docs: "The QObject class itself is reentrant. However, certain
rules apply when creating and using QObjects in a thread that is not the GUI thread."

Or: "The Signals and Slots mechanism can be used in separate threads, ...".
