Comment 4 Pavel Alexeev 2015-12-12 16:52:57 UTC 
Hm.

It works for me:

$ chm2pdf --book fuzzynet_1_2_0.chm 
PAGES: 394
BYTES: 1239185                                                                 
Written file fuzzynet_1_2_0.pdf
Done.

How it reproducible?
What python version are you use?
Comment 5 Raphael Groner 2015-12-21 13:11:39 UTC 
First, sorry for the long delay of my answer.

But still with the *original* file content:

> chm2pdf --book fuzzynet.chm 
GetArchiveInfo: #SYSTEM does not exist
Traceback (most recent call last):
  File "/usr/bin/chm2pdf", line 1116, in <module>
    main(sys.argv)
  File "/usr/bin/chm2pdf", line 1110, in main
    convert_to_pdf(cfile, filename, outputfilename, options)
  File "/usr/bin/chm2pdf", line 331, in convert_to_pdf
    html_list=get_html_list(cfile)
  File "/usr/bin/chm2pdf", line 106, in get_html_list
    lister.feed(topicstree)
  File "/usr/lib64/python2.7/sgmllib.py", line 103, in feed
    self.rawdata = self.rawdata + data
TypeError: cannot concatenate 'str' and 'NoneType' objects

I downloaded the file back from rhbz attachment, and all is fine now:

> chm2pdf --book fuzzynet-1.2.0.chm 
PAGES: 394
BYTES: 1239185                                                                 
Written file fuzzynet-1.2.0.pdf
Done.


> head -1 /usr/bin/chm2pdf 
#!/usr/bin/python

> /usr/bin/python --version
Python 2.7.10

In the meantime, as a workaround I use chmlib instead of chm2pdf.
