Issue found testing with Warnings Plugin version 2.6. Hudson installed on one
Linux platform and building on a remote Linux node. Using scons to build a
project that is a mixture of C/C++ using the GNU compiler. The Warnings plugin
does an excellent job of scanning the console output and identifying and
reporting warnings and errors.

Problem appears whil accessing Hudson and the Warnings Plugin, clicking on a
link that is supposed to pull open the source and jump to the line that
generated the warning/error. When link is clicked Hudson displays the
following content:

29 Can't copy file from slave to master: slave=rtre/utility/iicore/tst.c,
master=/var/hudson/jobs/BriansTestInvigBuild/builds/2009-04-14_11-03-
33/workspace-files/d31670b0.tmp

The file /rtre/utility/iicore/tst.c is directly under the Hudson $WORKSPACE
path. In my situation $WORKSPACE is '/var/hudson/workspace/TestBuild. and the
absolute path to the billtst.c source
is '/var/hudson/workspace/TestBuild/rtre/utility/iicore/tst.c'
