vlc crashed with SIGABRT in __assert_fail_base()

[Ricardo J. Moreira Teixeira]

Before it starts to play unity almost freezes and it appear only the window title bar doing a wooby thing. After the image appears on the window it stops, all the desktop freezing also and everthing's ok.
When the video stop the initial behaviour starts again and it appeared the apport crash report.

[Rémi Denis-Courmont (rdenis)]

Assertion failure inside XCB from Xlib from Qt4 GUI. Definitely not a VLC bug; VLC does not touch XCB directly (in this scenario).

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

VLC crashes when attempting to launch Preferences window. Preferences window does not display (just flashes in and out). Only the window borders of the preferences dialogue box are displayed.
