Well, source is a built-in command, so it  acts different if you are
using Bash in the sh (posix) mode instead of bash mode. So you may
need to give the full path to the file. From the bash man page:

source filename [arguments]
       Read and execute commands from filename in the current shell
       environment and return the exit status of the last command
       executed from filename. If filename does not contain a slash,
       file names in PATH are used to find the directory containing
       filename. The file searched for in PATH need not be
       executable.

       When bash is not in posix mode, the current directory is
       searched if no file is found in PATH. If the sourcepath
       option to the shopt builtin command is turned off, the PATH
       is not searched. If any arguments are supplied, they become
       the positional parameters when filename is executed.
       Otherwise the positional parameters are unchanged. The return
       status is the status of the last command exited within the
       script (0 if no commands are executed), and false if filename
       is not found or cannot be read.

So I don't think it is a bug, but a compatibility feature.
