Can you please tell if any applications in Debian repos are affected by this bug? You mentioned libqtgstreamer but it's a library — do you know if there is a concrete application that can be used to reproduce that crash? It is unlikely that we will be able to fix it, provided that upstream patch is not publicly available. So I am downgrading severity to make this bug not block the release of Debian Bullseye. This bug does not satisfy the criteria for critical anyway, because not the whole libqt5widgets5 library is broken, but only a specific use-case of it (which is also a deprecated one). Also I am removing the newcomer tag — newcomers won't have enough knowledge to be able to fix it. -- Dmitry Shachnev
