Bug#966174: okular

["Miguel A. Vallejo" <ea4eoz@gmail.com>]

After a small investigation in Debian's KDE mailing list we found the
affected PDF files were those digitally signed, and a simple
workaround was also found:

1.- Delete the .mozilla directory in your home directory

2.- Run Firefox. A new .mozilla directory should appear.

Now okular works just fine with these PDF files.

It has to be something related to poppler or libpoppler looking for
certificates in the .mozilla directory.

Also it is a case of an unexpected dependency of okular / poppler /
libpoppler with firefox that can affect no-firefox users, like me.
Okular doesn't work with digitally signed PDF unless you have a
working .mozilla directory, and this is only possible, as long as I
know, if you run firefox at least once.

Hope this helps.
