vlc crashed with SIGSEGV in exit()

[Jānis Kangarooo]

Binary package hint: vlc

Had open VLC with .avi file paused and had chrome open with YT video playing.
Sometimes when chrome has open YT videos all X crashes and gives the login screen.
This time after loging in and 5min later got this crash report pop up about VLC but not about X or chrome.

[Rémi Denis-Courmont (rdenis)]

There are really not one but two bugs here, one in X and one in VLC. First Your X server crashed. This triggered the Xlib error handler in VLC, which is notoriously buggy in VLC 1.0 and earlier, and therefore VLC crashed too. The good news is, the VLC bug should already be fixed in VLC 1.1.

The bad news is, because you only have the stack trace for VLC, the X bug can probably not be investigated.

Yeah, we'd need a full backtrace on the X crash, sorry.
