--- Comment #2 from d_tassos at hotmail.com ---
Sure no problem.

Actually this occurs on one of my systems but not the other, so indeed, most
likely it is not directly an RKward problem.

On the system that does crash, it now happens every time when I click on the
index when in a help page. What could be the problem? The two systems I use for
working with R/RKward both have the same OS (Manjaro) and are equally updated.
If it is a webkit problem any pointers were to look into? Below is the trace
from a test I just did.

Cheers
