    Description

      in my use case, i need to call QFontDatabase::removeAllApplicationFonts() before destroying the QApplication object, otherwise the next QApplication instance in the same process will crash.

      i'm not sure what is the best solution for this issue in qt, but it might be fine to simply call removeAllApplicationFonts() in ~QApplication.
