Well, you may be right. If your module calls:
  from report.render.rml2pdf import customfonts as cfonts
  cfonts.TTFSearchPath_Linux = cfonts.TTFSearchPath_Linux + ( '/my/path',)
it wouldn't work. 
However, I would still expect this to work:
  cfonts.TTFSearchPathMap['Linux'] = cfonts.TTFSearchPath_Linux + ( '/my/path',)

Note, however, that after any modification, you would better need to re-issue:
  cfonts.FindCustomFonts()
because there is a slight chance that this function had been called before your 
module's code is executed, and then it wouldn't consult the paths again.

Title:
  The TTFSearchPath changed at outside module is ignored

Status in OpenObject Server:
  New

Bug description:
  There are 3 variable defined in report.render.rml2pdf.customfonts module: TTFSearchPath_Linux, TTFSearchPath_Windows, TTFSearchPath_Darwin, all refers to tuple object. They are refereed in the TTFSearchPathMap dict like below:
TTFSearchPathMap = {
    'Darwin': TTFSearchPath_Darwin,
    'Windows': TTFSearchPath_Windows,
    'Linux': TTFSearchPath_Linux,
}

If at later time I make 3 TTFSearchPath variable refers to other tuple object (eg. change the search path), these changes won't affect the TTFSearchPath* in TTFSearchPathMap dict, as they are still refered to the original tuple object.

I propose to replace immutable tuple to list, thus all changes to these variable will count in the later process.

patch is attached
