Bug#673974: dch --increment does not create new section

[Marc Haber]

Package: devscripts
Version: 2.11.7
Severity: normal
File: /usr/bin/debchange

Hi,

dch --increment is documented as

       --increment, -i
              Increment either the final component of the Debian release  num‐
              ber  or, if this is a native Debian package, the version number.
              This creates a new section at the  beginning  of  the  changelog
              with  appropriate  headers  and footers.

This behavior has recently changed:

[62/557]mh at salida:~/tmp$ cat debian/control
Package: package
[63/558]mh at salida:~/tmp$ cat debian/changelog
package (1.0-1) UNRELEASED; urgency=low

  * Initial release. (Closes: #XXXXXX)

[64/559]mh at salida:~/tmp$ dch --increment <quit editor after typing a space>
Use of uninitialized value $_ in string eq at /usr/bin/dch line 764.
[65/560]mh at salida:~/tmp$ cat debian/changelog
package (1.0-2) UNRELEASED; urgency=low

  * Initial release. (Closes: #XXXXXX)
  *

I would have expected dch to leave the changelog entry for version
1.0-1 intact while creating a new one for 1.0-2

Greetings
Marc
