Details

Description:
I am using i3 as my window manager.

VLC crashes every time with a segmentation fault on opening any floating window dialog.

It also crashes when switching the player to fullscreen either by double clicking on it or using the i3 shortcut for making a window fullscreen. Interestingly this type of crash only happens if the VLC window is displayed on one specific monitor in my two monitor setup.

Additional info:
* vlc 2.2.4-5
* a stack trace of the crash for opening the preferences is attached

Steps to reproduce:
* open VLC
* open the preferences
   vlc_crash.log (6.9 KiB)
This task depends upon

The crashes stop when I switch the QT GUI style from "GTK+" to some other theme (like "Cleanlooks").

So it seems to be a problem with the interaction between the QT GTK+ theme and maybe the GTK theme I'm using (Adwaita).

This should generally be reported upstream, but Qt4 is EOL...

So it could be reported to VLC upstream as they're the ones using old, EOL'd libraries.

Closing as there's nothing we can do about this but wait for qt5-based vlc to be released. Qt4 is EOL and this won't be fixed upstream.
