Comment 9 for bug 1827194

Hopefully I'm adding the attachment correctly, and hopefully it contains some useful information.

I was unable to follow the instructions exactly as gdb would hang when pressing ctrl+c. I waited at least ten minutes but the prompt wouldn't appear. I had to kill totem outside of gdb to progress to where I could type in the backtrace command. Further, while the wiki suggests sudo should only be necessary for programs run with sudo, I was unable to attach the totem process without it. So that's what I did.
