Works fine with other QPA's (and global menu enabled) or with global menu disabled

Comment 1 Kai Uwe Broulik 2017-08-31 09:08:17 UTC
Works here both with global menu applet and title bar menu button. smplayer 15.11.0 on Qt 5.9.1 (compiled against Qt 5.5.1 though) and MPV 0.14.0
Comment 2 Antonio Rojas 2017-08-31 09:12:33 UTC
smplayer 15.11.0 also works here. Whatever triggers this has been introduced in a later version (reproducible at least with 17.8.0)

More precisely, in this commit:

On another machine I'm getting the segfault on close instead of on startup (still only with global menu + Plasma QPA)
Comment 4 Federico 2017-09-11 18:28:03 UTC
I can reproduce same segfault on smplayer 17.9.0 on archlinux with qt 5.9.1, kde 5.10.5 with global menu enabled.
Comment 5 Antonio Rojas 2017-11-10 08:23:47 UTC
smplayer 17.11 "fixes" this by forcefully disabling global menu


So feel free to close this if this is considered a valid solution for this on the KDE side.
