Hi,

Assuming you specified "debian/tmp/<path>" directly in your install
file, then a duplicate "debian/tmp" is expected on a failure (in compat
7 or later).

Since compat 7, debhelper will do a fallback to debian/tmp/<given-path>
if <given-path> does not exist (or the wildcard matches nothing).
Notably, debhelper does not check whether <given-path> already starts
with "debian/tmp/" or not before trying.

Thanks,
~Niels
