Public bug reported:
Upstream bug report filed at http://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=651642
This is related to Debian bug reports #630772 and #637737
When purging old kernels from the command line, multiple "Use of
uninitialized value $command" errors are displayed. These errors are
caused by the following code line:
return 1 unless defined && ! /^\s*#/; # Skip blank lines,
comments.
The code skips undefined input and comments, but the associated inline
comment claims that the intent was to skip blank lines and comments. I
resolved the problem locally by making the following change:
diff --git a/Debconf/ConfModule.pm b/Debconf/ConfModule.pm
index 8017202..20c084e 100644
--- a/Debconf/ConfModule.pm
