sorry, took me a while to figure:
- if i query from lastlog.de i get load-failed and
- from localhost i don't get load-failed
probably a timing issue. i've also rearranged the source code another
time. anyway, the core problem with load-failed seems to be the local
vs. remote target's runtime.

but this 'accessibility errors' are not really error messages related to
my problems of:
- load-failed and
- the webpage not being queried
correct?

you are correct in the observation that there is something odd going on.
the problem was that i built gojs with the old version and other parts
with the new version so i was mixing webkitgtk 2.4 with webkitgtk 2.8.3
which is a bad thing to do!
thanks for pointing that out! i'm fixing this right now but now i'm
facing a problem i had some time ago:

Perhaps you should add the directory containing `javascriptcoregtk-3.0.pc'

but the webkitgtk-2.8.3 only features libjavascriptcoregtk-4.0.so:

any ideas on that?

this libjavascriptcoregtk-4.0 vs libjavascriptcoregtk-3.0 thingy is
probably the main problem i'm having here, gojs relies on 3.0 and 2.8.3
features 4.0
is that assumption correct?
thanks very much for your help, very much appreciated!
