Kubuntu 16.04 I type a message and after I click "enter" in order to send nothing is sent, nothing is seen in the screen, my message is just disappeared. The funny thing is, sometimes it works, however I could not figure out yet any dependencies.
The bug report has no details e.g. what is the connection manager in use. It could be an issue on any level of Telepathy but most probably there was something with your CM. I'm closing it 'as is', feel free to add more info and reopen if needed.
