I can replicate this same error using the Ubuntu 15.04 package version
0.9.1-1.1ubuntu5. chm2pdf crashes on every possible invocation when I
try to convert the CHM of _Infinite in all directions, Freeman Dyson
1988 (
https://www.dropbox.com/s/9iwq6kiw6gie0ts/1988-dyson-infiniteinalldirections.chm
), despite it opening and reading fine in FBreader (but not Calibre).
Example:
$ chm2pdf --webpage 1988-dyson-infiniteinalldirections.chm foo.pdf
GetTopicsTree: file size = 0
