When I try to drill down on a warning from a project that is build on a slave
machine, I get the following error:

32 Can't copy file from slave to master:
slave../../project_sub_dir/config_items/../application_build/sourcefile.c,
master=C:\Documents and
Settings\csc\Desktop\HUDSON\data\jobs\MYPROJECT\builds\2009-09-01_16-35-00
\workspace-files\bedc4126.tmp

Maybe it's related to an issue with symbolic links, which are used extensivly
in our build scripts. Or it's an issue with the relative directories, but I
can't think of a way relative directories in my build scripts can affect hudson
plugins...
