Comment 5 for bug 1155343

Good catch on the licensing Sebastien.

I'm not a licensing expert either, but it does appear like I had at least made something of a mess by bundling that file, if not made something completely illegal.

To avoid any potential issue, I took the easy way out and dropped the bundle copy of pycanberra:
https://github.com/bochecha/ibus-cangjie/commit/e61f3513fc75b6fb341d8afbb204aabd5d0b065a

IBus Cangjie will now either use the system pycanberra (if it is available) or just not play any sound when the user makes an incorrect input (if pycanberra is not available).
