[yocto] IPK Package name contains illegal characters?

[Evade Flow]

After (finally!) getting all the required sources pre-mirrorred, I was
able to the build the 'discovery-image' in the meta-ivi layer in 2 hours
+ 17 minutes:

  http://git.yoctoproject.org/cgit/cgit.cgi/meta-ivi/

This was using package_rpm, though, so I thought I could do better by
changing conf/local.conf to contain:

  PACKAGE_CLASSES ?= "package_ipk"

It appears that this was going to be quite a bit faster, but after 1
hour it generated the error:

  *** Error: Package name  contains illegal characters, (other than [a-z0-9.+-])


The extra space between 'name' and 'contains' seems *very* suspicious,
but I don't know what to make of it. (The package name is an empty
string? Why?)  Any suggestions as to how I can debug this? The log file
doesn't show what command was attempted, so I really don't know where to
begin.

In case it's helpful, the tail-end of the output from running 'bitbake
-DD DLT-daemon' is appended below.  (NOTE: The exact same problem exists
for the AudioManager component of the meta-ivi layer...)
