Hi,
Since (at least) 07-Aug-2016 14:04, the all-popcon-results.txt.gz file
contains an invalid line:
Package: libfyba0-dbg 0 2 0 0
--> Package: libf erdp-ommon 0 0 0 1
Package: libg++2.8.1.3-dbg 0 0 0 1
That's (currently) line 54869. The "space" on the second line is actually
a 0xa0 character. This is making the package unusable.

You can see this happening here:

Patch attached. NB. the comment in the lookup section.
