vykar-gui - second tray-icon of vykar-gui in the tray

[goebbe]

Testing vykar-gui 0.19.0 on Linux Mint CE (22.3).

Issue: Sometimes a second "tray icon" of vykar-gui is displayed in the tray.

In the settings of vykar-gui, I have selected "start at login".
When I start my computer, vykar-gui is started automatically, as expected, with one tray-icon displayed.

Sometimes, after some time (e.g. several hours or overnight) of usage, a second "tray icon" appears in the tray.
Both tray-icons seem to be fully functional.
If I select "quit" in the right-click menu of one of the tray-icons, vykar closes and the two tray icons disappear.

Additional information:
I don't know if this is relevant: Before vykar-gui offered the "start at login" option, I already had my own solution running, in order to autostart vykar. I disabled my own solution, but perhaps this is triggered by config leftovers?

htop shows that there is only one instance (one tree) of vykar-gui running.

On this system, I never had similar issues before - so this seems to be something specific to vykar-gui.

This is not a new in 0.19 - I have seen this issue before, with older versions, too.

Additional observation:
If I manually start two instances of vykar-gui I get a different behaviour:

• two tray-icons of vykar-gui are displayed in the tray
• however, now they belong to two independent instances, i.e. if I close vykar-gui by using right-click, "Quit" on a tray icon - only one instance of vykar-gui is closed (the second instance of vykar-gui is not affected by quitting the first instance via the tray).
  This is different from the reported issue, where "Quit" in on tray icon will quit vykar-gui and remove both tray-icons in one go.
