Bug#844662: vlc crashes with segmentation fault immediately

Thu Nov 17 21:56:51 UTC 2016

Package: src:vlc
Version: 2.2.4-7
Severity: important

Dear Maintainer,

vlc crashes immediately after start. If run from command line, it shows
a segmentation fault:
 vlc
 VLC media player 2.2.4 Weatherwax (revision 2.2.3-37-g888b7e89)
 [0000559418a65148] core libvlc: Running vlc with the default interface.
 Use 'cvlc' to use vlc without interface.
 Segmentation fault

I tried both vlc 2.2.4-7 in testing and vlc 2.2.4-8 from unstable (some vlc-related packages were
updated with it too), the same happens.

I ran it through valgrind, it seems that the problem is related to Qt5:
