Re: [evince] ev_document_factory_get_document not loading pdf file

[Richard Shann <richard shann virgin net>]

Hi Hib,

I have had some feedback from Jeremiah who is working with the Mac on
the evince library build, he ran the call to

ev_file_get_mime_type("file:///tmp/DenemoYBsSdY/denemoprintB.pdf", 1, NULL)

in gdb and got back the string

 "text/plain"

So he appended ";text/plain" and ";application/octet-stream" for good
measure to the pdfdocument.evince-backend file:

MimeType=application/pdf;application/x-bzpdf;application/x-gzpdf;application/x-ext-pdf;text/plain;application/octet-stream

but reports it still didn't load.

He says he is still hacking so there is no need to respond to this
unless you have a specific idea (e.g. about that "text/plain" thing)
that will help.

Thanks again,

Richard
