Comment 6 for bug 1672166

PYTHONPATH changes would more likely result in tracebacks, rather than subtle changes to word suggestions, in particular since this mixes Python 2 with Python 3 packages. Not saying it's impossible, but I doubt that's the reason.

We'll have to check everything systematically. Please run this
$ gsettings list-recursively org.onboard | grep -v snippets >onboard-settings.txt
and attach onboard-settings.txt.

Then run onboard again with more debug output,
$ onboard -d atspi 2>&1 | tee onboard-debug.txt
focus a different terminal, type a word there, focus gedit, type a word there, then exit onboard (Ctrl+C is fine) and attach onboard-debug.txt in another post.
