After upgrading all Qt packages from 5.14.0-r3 to 5.14.1, non-KDE Qt programs (such as net-misc/nextcloud-client and net-wireless/wpa_supplicant[qt5]) started crashing with SIGSEGV och SIGILL in /usr/lib64/qt5/plugins/styles/breeze.so. KDE programs worked, though. Example messages in dmesg: [ 51.198088] python3.6[4735]: segfault at 4 ip 00007f63c8c46360 sp 00007ffd3827cfc8 error 4 in breeze.so[7f63c8c1b000+51000] [ 132.765380] traps: torbrowser-laun[4365] trap invalid opcode ip:7f897efa8450 sp:7ffeb1f81788 error:0 in breeze.so[7f897ef7b000+54000] Arch Linux has the same bug (https://bugs.archlinux.org/task/65291), which they solved by revbumping their version of kde-plasma/plasma-integration. Sure enough, when I rebuilt kde-plasma/plasma-integration-5.17.5 against Qt 5.14.1 things started working again.

@pesa: Maybe we should add fine-grained subslot to qtgui as well... suppsedly also kwin is affected by this more often between point releases.
