Hi,

Confirmed (without the dh-exec layer) and is a regression since
debhelper/10.6.

Short term work arounds are:

 * Not using dh_install for this particular file/folder.
 * Rename manually without dh-exec and use dh_install on the already
   renamed file (with escapes).

Neither are optimal, but it is the best I can provide until the fix.

(Technically, you can also escape the brace as a work around for
debhelper - but I suspect it will still cause breakage as dh-exec then
might create the file with a literal backslash).

Thanks,
