Warning W155010: from Inspect tool

I'm getting this warning from the inspect tool
 
"boost-no-inspect" svn: warning: W155010: The node
'I:\boost-sandbox\guild\quickdox\libs\quickdox\doc' was not found. svn: E200009: Could not display
info for all targets because some targets don't exist
 
The folder
 
I:\boost-sandbox\guild\quickdox\libs\quickdox\doc
 
definitely exists,
 
(I have copied and posted the address into Windows explorer).
 
but there is no evidence that it is in SVN - the whole I:\boost-sandbox\guild\quickdox folder isn't
in SVN (though I think it might have been years ago?). 
 
I have also moved this folder recently to make it Boost-layout correctly /libs/quickdox/....
 
I have done a cleanup on Boost-sandbox, including the 'cache'.
 
I have considered adding and update and doing a SVN clean-up to try to resolve this, but I believe
boost-sandbox is locked (and I would not like to upset the delicate GITerization process).
 
Other Suggestions?
 
Thanks.
 
Paul
