Bug#884675: mate-panel: Telegram icon disappeared from notification area

[Francesco Potortì]

Package: mate-panel
Version: 1.18.6-1
Severity: normal

This is the bug described in
<https://github.com/mate-desktop/mate-panel/issues/537#issuecomment-352205734>

On Debian testing it happens with Mate 1.18.0, Telegram 1.2

For some reason the above issue was closed upstream, but the problem is
still there.

In addition, and maybe related to that, I can observe this in the logs:
