I built yelp inside a chroot (without X) and ran
docs/libyelp/libyelp-scan directly. The resulting backtrace from the
crash is attached. This looks to me like it's webkit2 related, so I'm
reassigning the bug. The dbus warning is a red herring fwiw.
The binary crashes even when installing dbus and running with
dbus-run-session.
Berto, would be great if you can have a look.
Cheers,
Michael
