Goldendict tray icon error on screen lock

[Evgenii Frolov]

On ubuntu 16.10 launching Goldendict (v. 1.5.0~git20160508.g92b5485-1.1) creates a tray icon in the ubuntu panel tray area.
The icon is unexpectedly changed to a crossed red circle on black background on screen lock.

Steps to reproduce:
1) launch goldendict
2) lock your screen
3) unlock your screen

Expected behavior:
The goldendict icon that's appeared after step 1) should be there unchanged after screen unlocking.

What happened insted:
The goldendict trayicon is changed to an error sign (crossed red circle on black background) after screen unlocking.

PS I believe, one can catch the fact that the icon changes right before the lock.
PPS DropBox and Telegram icons are not affected.
PPPS Restarting goldendict fixes the problem.
PPPPS what can I do to help with dealing with the bug?

Status changed to 'Confirmed' because the bug affects multiple users.
