[debhelper-devel] Bug#818933: dh_install segfaults with 755 .install files, which don't have a shebang

[Matthias Klose]

Package: debhelper
Version: 9.20160115

dh_install segfaults with 755 .install files, which don't have a shebang

    dh_install -a -O--parallel
Segmentation fault (core dumped)
dh_install: problem reading debian/libcmis-0.5-5v5.install:
make: *** [binary-arch] Error 139
debian/rules:23: recipe for target 'binary-arch' failed

Saw this when accidentally adding x permissions to an install file which didn't 
need ones. So maybe add a better error message, or check that the install files 
has a shebang if it's executable?
