Duly noted.

I am hitting a brick wall in the Chinese Ubuntu forum.  It turns out that
nobody is using the ibus-libpinyin input method.

Would you be interested in using, as part of your daily routine, an input
tool that can suddenly crash and cannot be recovered until you delete all
the vocabulary that you have painstakingly built?  I won't blame them.

Switching to a different Chinese input method is much more involved than
you may think.  Even temporarily.  I might be able to personally force one
or two Chinese Ubuntu forum participants to test your proposed changes.
But that's about it for now.
