[pkg-gnupg-maint] Bug#848413: dpkg-maintscript-helper: error: dpkg: error: version '' has bad syntax: version string is empty

[Elimar Riesebieter]

Package: dirmngr
Version: 2.1.16-3
Severity: important

After an update on a powerpc machine I get:

dpkg-maintscript-helper: error: dpkg: error: version '' has bad syntax: version string is empty
dpkg: error processing archive /var/cache/apt/archives/dirmngr_2.1.16-3_powerpc.deb (--unpack):
 subprocess new pre-installation script returned error exit status 1
dpkg-maintscript-helper: error: dpkg: error: version '' has bad syntax: version string is empty
dpkg: error while cleaning up:
 subprocess new post-removal script returned error exit status 1

A reinstall via apt gets the same error.
