[poppler] Fwd: Too many fonts embedded in a document?

[Alex Korobkin]

Hi team,

I have this nice PDF [1], which when converted to ps with the command
$ pdftops -level3 -r 300 ./P020110106297943134404.pdf
produces 20 Mb file with poppler 0.18.4, and 1.7 Gb (!) file with poppler
0.22.3

Looks like poppler 0.22.3 embeds way too many fonts:

$ grep -n CIDFontName P020110106297943134404-0.22.3.ps | wc -l
168

$ grep -n CIDFontName P020110106297943134404-0.18.4.ps | wc -l
12

Why could such a thing happen?
This was tested on Ubutnu 12.04, which comes with poppler 0.18.4. 0.22.3 I
compiled myself using the same configuration switches as Canonical uses for
0.18.4. Is there something that I could have missed in terms of
configuration?

poppler-data is 0.4.5 for 0.18.4 and 0.4.6 for 0.22.3.

Your help is appreciated.
