Weird dbus error with the systray menu on Linux

[NiLuJe]

Calibre 5.0.1, on Linux x86_64 (Gentoo), on Plasma 5/X11.

I'm getting a weird dbus error when attempting to show the systray menu (the icon itself is fine), which prevents said menu from actually showing up.
Full debug log attached (ignore the not-yet-updated plugins, and basically jump to the end. The message shows up on startup, and is repeated each time one attempts to open the systray menu).

I initially thought it was a weird build issue with my source builds, but it turns out I can reproduce it with the official binary releases, hence this report ;).

Probably something in the dbus binding for the menu broke with python 3,
will look into it when I have a moment.

Relevant code is in dbus_export/menu.py if you wish to investigate.

I have a rather strong allergy to anything dbus-related (^^), but I'll see if anything jumps out at a quick glance, thanks ;).

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.

That did the trick, thanks ;).
