Bug#972645: gnome-builder does not start without flatpak package installed

[nodiscc]

Hello,

> This might mean that gnome-builder has an undeclared dependency on
something else that is depended on by flatpak.

I just ran sudo apt purge flatpak, which resulted in flatpak* and
flatpak-builder*
being removed. After this, I can reproduce the problem again (crash at
startup)

> Those look like messages from gdb?

It seems related as after uninstalling gdb, I no longer get these messages.
Instead:

    $ gnome-builder
    Segmentation fault

> If you create a new user account on the same system (so your home
> directory and personal configuration are not in use), can you run
> gnome-builder successfully as that user?

No, it also crashes with the same error messages
