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

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?

[Sebastian Ramacher (s-ramacher)]

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.

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.
