Summary:                    get_filename_component returns blank
Description: 
Command get_filename_component fails to return the name of the file if its input
string is not simple. This works:
get_filename_component(EDB "${CMAKE_INSTALL_PREFIX}/etc/emppack.db" NAME)

but the following fails
set(EMP_DB_FILE  "${CMAKE_INSTALL_PREFIX}/etc/emppack.db" CACHE FILEPATH "name
of the Emppack data base file. Full path must be included")
get_filename_component(EDB "${EDB_DB_FILE}" NAME)


Steps to Reproduce: 
set(EMP_DB_FILE  "${CMAKE_INSTALL_PREFIX}/etc/emppack.db" CACHE FILEPATH "name
of the Emppack data base file. Full path must be included")
get_filename_component(EDB "${EDB_DB_FILE} " NAME)
message(" this is the dbfile: ${EDB}")

Additional Information: 
I could reproduce the error using cmake 2.8.7 and 2.8.9 on an updated Ubuntu
12.04 and on a RHEL 6.3.
