Bug 507826

SUMMARY
When I switch the Virtual Keyboard from the default "Maliit" to "IBus Wayland" (System Settings -> Keyboard -> Virtual Keyboard), address autocompletion in KMail stops working. I can reproducibly enable or disable address autocompletion just by switching virtual keyboards and hitting "Apply".

I would love to be able to have both -- IBUs Wayland (so I can type in Unicode characters by pressing CTRL+SHIFT+U followed by the character code) as well as address autocompletion in KMail.

STEPS TO REPRODUCE
1. Go to System Settings -> Keyboard -> Virtual Keyboard
2. Select "IBus Wayland" and hit Apply
3. Attempt to have KMail autocomplete an address that is being typed in the composer window.

OBSERVED RESULT
Address is not being completed automatically.

EXPECTED RESULT
Address should be completed automatically.
