Comment:

 This can be fixed by cherry-picking the following commit from master:

 {{{
 commit cf1d9751e7ca85e9b3284ad57882958b8dc73d16
 Author: Edward Z. Yang <ezyang at cs.stanford.edu>
 Date:   Tue Apr 7 09:08:54 2015 -0500

     Don't repeat package key with -dppr-debug when package info is
 missing.

 }}}

 as well as applying the attached Phab diff.

 When I cherry-picked, I had to fix a minor parenthesization wibble:

 {{{
