Comment 1 Rolf Eike Beer 2020-07-09 13:20:26 UTC 
Please start kgpg in a terminal and report the output.
Comment 2 Sebita 2020-07-09 21:44:37 UTC 
Every time I want to start the app:
QCommandLineParser: argument list cannot be empty, it should contain at least the executable name

journalctl says:

jul 09 18:38:08 redone.casa kgpg[1811]: QCommandLineParser: argument list cannot be empty, it should contain at least the executable name
Comment 3 Sebita 2020-07-09 21:46:04 UTC 
I started kgpg from terminal logging output. Nothing happened.
I tried to start kgpg from KDE menu and that was the output.
Comment 4 Christoph Feck 2020-07-21 08:08:53 UTC 
The crash is in the Qt/glib event loop integration, maybe not being thread-save (Thread 2 and 21 are also running g_main_context_iterate.constprop).

I suggest to report this issue to glib developers via https://developer.gnome.org/glib/stable/glib-resources.html
