The command line workaround recommended by setroubleshoot is incorrect when the offending path contains spaces (see bug 537754).
An example recommended command line is:
/usr/sbin/semanage fcontext -a -t execmem_exec_t "/opt/Aptana Studio 2.0/AptanaStudio"
which fails due to the spaces not being escaped.
