Strange "vsn" value in Applications loaded pour cb_admin

[lc3t35]

As you can see at https://github.com/ChicagoBoss/cb_admin/issues/35 snapshot, there is a strange value of cb_admin:vsn in Applications loaded, instead of "0.7.1' we have "/bin/sh: 1: 0.7.1: not found" ...

Searching : cb_admin.app.src : {vsn, "0.7.1"} OK cb_admin_admin_controller.erl : {modules_loaded, ModulesLoaded} is set by application:info() Searching for "loaded" in boss, i went to boss_load.rel :

make_computed_vsn({unknown, Val} ) ->Val;
make_computed_vsn(Cmd ) ->
    VsnString = os:cmd(Cmd),
    string:strip(VsnString, right, $\n).
