Bug Description
While loading a PDF document, the number of image providers is set based on the value returned by QThread:
On the latest ARM architectures, some of the cores of a SoC may be temporarily turned off, in order to improved the power consumption.
This may cause a wrong number of initialized image providers (e.g. only 2 image providers on a quad-core CPU).
