A problem occurs when we write the ConverterCache index file. This action is instantiated in the destructor of the 'static ConverterCache' object. The use of QFileInfo at that point leads to a crash.
It is maybe not a good idea at all to put part of the functionality in a destructor, especially not when we do not delete the object ourselves and when this functionality uses external libraries etc.
