Per downstream report, this is caused by a user misconfiguration (no timezone configured)
This seems like a Qt bug. QLocale::system is supposed to fallback to the C locale, but QLocale::toString is crashing in Qt's backend code. https://doc.qt.io/qt-6/qlocale.html#system > The system locale may use system-specific sources for locale data, where available, > otherwise falling back on QLocale's built-in database entry for the language, script and territory the system reports.
(In reply to Noah Davis from comment #3) > This seems like a Qt bug. QLocale::system is supposed to fallback to the C > locale, but QLocale::toString is crashing in Qt's backend code. Note that the issue is misconfigured timezone (ie. missing /etc/localtime), not locale. Still, Qt should handle it gracefully.
Can confirm the issue.
