Issue

When starting parlatype, it crashed. Starting it from the command line results in the following output:

**
GLib-GIO:ERROR:../gio/gdbusconnection.c:4217:invoke_get_property_in_idle_cb: assertion failed: (error != NULL)
Bail out! GLib-GIO:ERROR:../gio/gdbusconnection.c:4217:invoke_get_property_in_idle_cb: assertion failed: (error != NULL)

Thanks for you report! Is this reproducible? I need a backtrace to know what's going on. Frankly, I haven't done that before with a Flatpak, my knowledge is mostly from here, scroll down to Flatpak: https://blogs.gnome.org/mcatanzaro/2021/09/18/creating-quality-backtraces-for-crash-reports

$ flatpak install org.parlatype.Parlatype.Debug//stable
$ flatpak install org.gnome.Sdk//40
$ flatpak install org.gnome.Sdk.Debug//40

I understand you can now let the app crash and do this:

$ flatpak-coredumpctl org.parlatype.Parlatype

As I haven't had a crash with a Flatpak yet, I'm not sure if that's really enough.

Another thing that might help, although probably not much, is to run Parlatype like this:

G_MESSAGES_DEBUG=parlatype flatpak run org.parlatype.Parlatype

Please post the output of this and if possible also the backtrace.

Same problem here building from source, so I don't think is flatpack related:

~ $ G_MESSAGES_DEBUG=parlatype parlatype

Version 3.0 run without problems.

I discover that this problem is related to KDE Connect. If I kill kdeconnectd then Parlatype runs fine. So maybe its something related to MPRIS. Any ideas? Also don't know if this is a problem with Parlatype or KDE Connect, but its clear that the two don't get along well.

KDE Connect version: kdeconnect-22.08.0

Thank you for your report and thanks @polirritmico for triaging this bug. I can reproduce it and will fix it.
