[Python-modules-team] Bug#898211: python3-pyqt5: Changes in 5.10.1 causing a startup crash in Cura

[Gregor Riepl]

Package: python3-pyqt5
Version: 5.10.1+dfsg-1
Severity: important
Tags: patch

Dear Maintainer,

Upstream introduced a bug into PyQt5 5.10.1 that broke Cura:
https://github.com/Ultimaker/Cura/issues/3438

Maintainers in ArchLinux and Ubuntu have already applied a backported patch
that fixes the bug.

ArchLinux bug: https://bugs.archlinux.org/task/57992
ArchLinux fix:
https://git.archlinux.org/svntogit/packages.git/commit/trunk/pyqt5-cura-
crash.patch?h=packages/pyqt5&id=2126378a110aab1422cec64426eb4ca979dfc968
Ubuntu bug: https://bugs.launchpad.net/ubuntu/+source/pyqt5/+bug/1766092
Ubuntu fix: https://launchpad.net/ubuntu/+source/pyqt5/5.10.1+dfsg-1ubuntu2

Please apply this patch to PyQt5 5.10.1 and release a new Debian version as
soon as possible. Until then, Cura will not run with the current PyQt5 version
in sid and buster.

Thank you.
