Bug#843511: libqt5widgets5: Some Qt applications segfault on startup
Package: libqt5widgets5
Version: 5.7.1~20161021+dfsg-5
Severity: grave
Justification: renders package unusable
Dear Maintainer,
After upgrading to Qt 5.7, some applications fail to launch an segfault instead.
For example, here's lxqt-powermanagement:
#0 0x0000000000000000 in ?? ()

This seems to have something to do with the platform integration. I am using LXQt as my DE.
I noticed lxqt-qtplugin has not been re-build and is not even part of the transition, maybe it should be?
I have version 0.11.0-3 installed.
Kind regards,
Ralf
