Ok, so socket files should be created as 

/tmp/rkwardXXXXXXXX and
/tmp/rkdXXXXXXXX

where the Xs will differ on each invocation. These files shall
disappear as soon as the backend has connected to them, however, for the
"rkdXXXXXXXX" socket this will not happen until something is plotted.

So, after starting (without closing the frontend), check the contents
of /tmp. You should at least see the "rkdXXXXXXXX" socket, with
permissions something like:

  srwxrwxr-x 1 thomas thomas        0 Jul 29 19:30 rkdIcQVLfKK=

Now try 

 socat - UNIX-CONNECT:/tmp/rkdIcQVLfKK

Sending anything will only get you an error message, but does the
connecting work?

Regards
Thomas
