Jeremiah - here is the response from the evince list about the
text/plain value.
Can you run the
ev_file_get_mime_type("file:///tmp/DenemoYBsSdY/denemoprintB.pdf", 0,
NULL)
call he suggests, the different second parameter is a boolean which
toggles between "fast" mime type detection and slow. We were calling for
"fast".He gives a helpful reference to where in the code this is going on ... email is below Richard 8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8>< On Tue, Mar 19, 2013 at 9:48 AM, Richard Shann <[email protected]> wrote: > 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" "text/plain" is obviously not correct, it should be something with 'pdf' in it I guess. Could you see what ev_file_get_mime_type("file:///tmp/DenemoYBsSdY/denemoprintB.pdf", 0, NULL) gives back as well? Evince code for mime type detection is in libdocument/ev-file-helpers.c. I'm afraid it is a bit unpredictable when glib fails to find the correct mime-type/content-type. On Tue, 2013-03-19 at 00:46 -0500, Jeremiah Benham wrote: > I decided to hack on evince a bit.
