Re: [Denemo-devel] [evince] ev_document_factory_get_document not loading pdf file

[Richard Shann]

Jeremiah -

I have received this very informative reply from Hib Eris - would you like me 
to put a print-out of ev_file_get_mime_type() into the sources
or are you able to do 

call ev_file_get_mime_type ("file:///tmp/Denemou<xxx>/denemoprintB.pdf", 1, 
NULL)

while in gdb? (The temp directory will be <xxx> and you need either A or B 
depending).

or can you just check /usr/lib/evince/4/backends/pdfdocument.evince-backend 
first (I would guess it is ok)
and look at the other fix - the "register the pdf mime type somewhere in your 
OS specific mime type
store" thing.

Previously, I've run into the same problem when porting Evince to
Windows. It has something to do with Evince' mime-type
detection/handling. I think there were several issues with it.

First step to fixing this is to see what this evince function returns:

mime_type = ev_file_get_mime_type (uri, TRUE, error);

If that returns 'application/octet-stream', I guess you need to
register the pdf mime type somewhere in your OS specific mime type
store.

If the mime type is something like 'application/pdf', then make sure
the returned mimetype is specified in the file
/usr/lib/evince/4/backends/pdfdocument.evince-backend.
