Can't run gnome (?) applications

[hazg]

There are no windows in gnome programs. From the terminal everything runs correctly.

I.e. I can see in htop for example that they are running.

dconf-editor, deja-dup, gnome-software for example.

Ubuntu 21.04

im using it by UbuntuBudgie/budgie-lightpad-applet in Budgie

but from terminal - It's OK

I've debugged this. The issue is that these apps are activated via dbus - however, due to lightpad closing immediately after "launching" the application, the dbus activation is not fully started and hence the application does not appear.

What is needed is that lightpad needs to understand about dbusactivatable and wait until the dbus signal appears before closing.

budgie-desktop shows how this could be done

Note - this is a very dirty patch I'm including in our (ubuntu budgie) backports PPA - I won't do a PR because really the code needs proper dbusactivatable handling as outlined above.

@fossfreedom thank you for the contribution. I've very busy lately with my main work. I'll try to fix this issue as soon as possible. Regards!

We need investigate in more deep DBus activatable features... thank @fossfreedom for the example code of Budgie Desktop... DBus things will be features for next major release. For now, I implemented you temporary patch. Thank you!
