Bug#983025: libqt5widgets5: Segfault with QGLWidget class. Fixed Upstream
Package: libqt5widgets5
Version: 5.15.2+dfsg-4
Severity: critical
Tags: upstream newcomer
Justification: breaks unrelated software
Dear Maintainer,
Recently i found a bug in QGLWidget (one of the widgets included in
libqt5widgets5) that
creates a segfault. This bug was accepted as upstream bug 86582
(https://bugreports.qt.io/browse/QTBUG-86582)
It was confirmed and fixed by the Qt people, unfortunately, it has been
committed to the
5.15 LTS branch of their development which is no longer accessible to the
OpenSource licensees
QGLWidget has been a deprecated Widget for some time now, and many software
changed to
QOpenGLWidget alternative, which does not exhibit this problem, but other
pieces of the debian
system (e.g. libqtgstreamer; also deprecated but still in debian repos) uses
it.
In the issue tracker of the Qt project the likely cause of the bug is
commented, but the actual
fix is not detailed (or i do not know how to access it)
Anyways, i want to put this here to kee everyone informed about this.
