I am using LXDE with Parabola (a libre derivative of Arch Linux). When I log in to the desktop environment, a window pops up with the following error:

GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: Cannot determine user of subject

What does this error mean and is it anything serious? What can I do to fix the problem?

The underlying issue seems to be the same as this question. The polkit authentication agent cannot register with polkit, which is causing the error window in LXDE.
