Both stable versions of smplayer (16.1.0 and 16.11.0) do not start - only message "Segmentation fault" I can see. In syslog I found this: kernel: smplayer[11292]: segfault at 0 ip (null) sp 00007ffc0c86af88 error 14 in smplayer[400000+336000] kernel: smplayer[11317]: segfault at 0 ip (null) sp 00007ffe6f2fef78 error 14 in smplayer[400000+336000] I recompile smplayer with USE=-qt5 qt4 and it works.

Also media-video/vlc-2.2.6 USE="qt5 -qt4" ends with "Segmentation fault". Recompiled with USE="-qt5 qt4" it works fine!? At last media-video/kaffeine-2.0.9 quit with "Segmentation fault". Use=qt4 is here not in portage.
