bug#64605: HandBrake 1.5.1 hangs on startup due libQt5Qml
HandBrake 1.5.1 hangs on startup and `dmesg` show the following error ``` QQmlThread[]: segfault at 0 ip 000 sp ... error 4 in libQt5Qml.so.5.15.8 ``` After some research I found a similar issues on NixOS: - https://github.com/NixOS/nixpkgs/issues/32577 - https://github.com/NixOS/nixpkgs/issues/177720 and a solution: https://github.com/NixOS/nixpkgs/pull/197010 Looks like the issue is related with QML disk cache, and after test ruining *handbrake* with `QML_DISABLE_DISK_CACHE=1` works fine ``` QML_DISABLE_DISK_CACHE=1 ghb ``` signature.asc Description: PGP signature

Have you searched if an issue was known about it? Their tracker is at https://bugreports.qt.io/. -- Thanks, Maxim

Checking there looks like is already reported a similar issue https://bugreports.qt.io/browse/QTBUG-58508, I think that happens in Guix/Nix becase QT is trying to write inside the profile path signature.asc Description: PGP signature
