Crash in QFontDatabasePrivate::ensureFontDatabase() on exit

    XMLWordPrintable

Details

    • Android

    Description

      We’re sometimes seeing the following fatal error in QFontDatabasePrivate::ensureFontDatabase() when users are exiting our Android app:

      QFontDatabase: Must construct a QGuiApplication before accessing QFontDatabase

      Here is the full stack trace (click "Full Stack Trace" on that page to show it).

      We’re seeing this with the latest Qt 6.8.1 and have see it with earlier Qt releases including 6.5.3. This is probably a duplicate of QTBUG-109463, which is tagged as Linux/X11 specific.
