Can you give a link to a video that triggers the crash?
Created attachment 110286 [details] example of video There is a small video file, but I also tried mp4 and mkv, situation repeats.

On my Mageia 7 x86-64 system dragon using phonon-vlc plays this file fine, and so do vlc and mpv. dragon cannot play it using the gstreamer backend but neither can gst123. dragon using gst can play fine an .mp4 file I have.
Created attachment 110400 [details] New crash information added by DrKonqi dragon (17.12.1) using Qt 5.10.0 - What I was doing when the application crashed: - Custom settings of the application: Hello. So, I tried play it with phonon-vlc backend. It plays. And after repeating playing that applicaton just crashes again. -- Backtrace (Reduced): #6 0x00007fa2a97213e5 in __memmove_avx_unaligned_erms () at /lib64/libc.so.6 #7 0x00007fa2aa482b8b in QUrl::toString(QUrlTwoFlags<QUrl::UrlFormattingOption, QUrl::ComponentFormattingOption>) const () at /lib64/libQt5Core.so.5 #8 0x00007fa2aa483060 in QUrl::toDisplayString(QUrlTwoFlags<QUrl::UrlFormattingOption, QUrl::ComponentFormattingOption>) const () at /lib64/libQt5Core.so.5 #9 0x000056472b7bc830 in Dragon::TheStream::profile() () #10 0x000056472b7c1a82 in Dragon::VideoWindow::eject() ()
That's a different crash.
Cannot open example video bin file in Dragon Player in both X11 and Wayland - if phonon gstreamer package is installed - Dragon Player just starts without any error and opening of the file - if phonon vlc package is installed - detached VLC Media Player window is shown with played video Plasma: 5.12.4 Apps: 18.04.0 Frameworks: 5.45.0 Qt: 5.10.1 Kernel: 4.14.36-1-MANJARO OS: Netrunner Rolling Video: Intel 4400 Driver: xf86-video-intel 1:2.99.917+823+gd9bf46e4-1 Screen: 1600x900 wayland-protocols 1.13-1 wayland 1.14.0-1
