bug#14418: 24.3; TAB key seems don't work fine with GNU Makefile

[Orlando Iovino]

When I compile with *Tools > Compile ...* and then I press TAB for
auto completation of a target name, in the minibuffer appears:

apply: Wrong type argument: stringp, nil

Is it a bug?

Best regards,
Orlando Iovino
