Hey,

first of all, sorry for the late reply!

Yes, it seems that the webkit_settings_new() call in liferea checks
whether XComposite is enabled, and that fails if there's no X Session.

I'm not sure if this is a webkit bug, but I reported it upstream
anyway.

Possible solutions if you don't want to have a full-featured X
session:

- Run g-ir-scanner with xvfb-run
- Set the environment variable WEBKIT_DISABLE_COMPOSITING_MODE=1 when
  running g-ir-scanner

The latter is probably the easiest option.
