Relatively recently I started seeing this annoying pop-up window: "Failed to apply network settings org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper exited with unknown return code 1" from blueman-applet. It turned out that /usr/libexec/blueman-mechanism has '#!/usr/bin/python ' as shebang (please not extra space at the end). This extra space confuses shebang fixing code as it tries to match with python$ which is not the case here: debug output: .. * Fixing shebang in usr/libexec/blueman-mechanism. + read -r + LAST_E_CMD=einfo + return 0 + [[ ! -n '' ]] + [[ #!/usr/bin/python == *python\ * ]] + sed -i -e '1s:python$:python2.7:' /var/tmp/portage/net-wireless/blueman-1.23_p20140717-r1/image/usr/libexec/blueman-mechanism ...

Oh, that's why it is happening! And I blamed bluez5 all the time ;). Thanks for the report, I'll get straight to it and try to find a non-obscure solution :).
+ 04 Sep 2014; Michał Górny <mgorny@gentoo.org> python-utils-r1.eclass, + tests/python-utils-r1.sh: + Preserve all whitespace in shebangs, and add regression test for that. Also, + prevent filename expansion when word-splitting it. Bug #522080.
