If a debian/control file containing a comment line followed by a blank line is processed by Sources.iter_paragraphs with use_apt_pkg=False, it silently fails to iterate stanzas. Processing the same file with Packages.iter_paragraphs succeeds. Stripping either the comment or the blank line succeeds.
Failing example: ``` # A comment Source: abcd Section: unknown Priority: extra Build-Depends: xyzzy ``` Successful example: ``` # A comment Source: abcd Section: unknown Priority: extra Build-Depends: xyzzy ``` We are using version 1.40-3
