Please use gdb --args vlc http://youtu.be/M-129JLTjkQ?fmt=22 and then
enter r to launch vlc. Once it crashes, enter bt to get the backtrace.

For Debian I'd link to https://wiki.debian.org/HowToGetABacktrace. This
should also work under Ubuntu, but you don't need to add additional
sources for the debugging symbols.

[Bug 1752190] Re: vlc segfaults on laptop

[gregrwm]

ran it again just now, vlc -vvv is attached.  a dialog came up offering
to send a bug report to help the developers, i pressed continue, heard
nothing further, did it send it?  where?  that would include the
backtrace, right?

Please provide the output of vlc -vvv up to the crash. Please also
provide a backtrace.
