[Impact]

* Users of KDE telepathy will experience this problem (always) when
opening first conversation window from the contact list.

[Test Case]

* Install KDE Telepathy, configure a Hangout account, double click a
user from contact list and experience the error
"org.freedesktop.Telepathy.Error.NotAvailable: Handler no longer
available" coming from notification popup.

[Regression Potential]

* Could make KDE Telepathy to stop working (unlikely).
* Tested in my own Xenial installation.
* Fix already released upstream (KDE).

[Other Info]

* Original bug description:

The bug reporter popped up while uploading the report on a different
bug. I have no idea what happened. I did not write down the error
message (hopefully the auto-uploader takes care of that for me), but it
seemed to indicate some portion of the log viewer crashed (perhaps the
log viewer for my other bug's crash report ui).

Description: Ubuntu Xenial Xerus (development branch)
Release: 16.04

ktp-text-ui isn't a package apt-cache policy can find, so I do not know
what the relevant version information is.
