Next time this problem occurs, please look in /var/crash for .crash files. If any are found then please upload them using this command only:

  ubuntu-bug /var/crash/YOURFILE.crash

And then add a comment in this bug telling us the newly-created bug ID.

[Jonathan Avraham (shambler-com)]

Thanks for your input, Daniel, but I just easily reproduced it (just flip the input source bach and forth, no need to even turn the TV off) and no crash file was created. /var/crash only has 4 crash files, none of which are from today.
