dbus-daemon sigsegv, apport cannot report it: expected core size ...

[LGB [Gábor Lénárt]]

At almost every boot and login after a while I get a "Ubuntu 18.10 has experienced an internal error" window. However it says, coredump size is too small (see attached screenshot).

Also no idea if it is related but touchpad of the notebook does not work only external mouse. This is a fresh 18.10 install on this new Lenovo L580 notebook, live version of ubuntu worked fine with touchpad and there was no window on dbus like that. However after the install it worked only once, then not anymore, regardless of reboot, powering off and on etc, and usually the mentioned internal error window is shown.

OK, the touchpad issue is not related at all, there is a kernel driver explanation of that. Now it works (the touchpad) but still, the mentioned dbus error message occurs from time to time, not so consistent though now.
