Thank you for your patience and your help, Diederik. By now I've figured out 
the problem. When running okular from a terminal, it said:

$ okular /path/to/file.pdf.gz
   ...
   okular(3581)/okular (app) Okular::Document::openDocument: No plugin for 
mimetype '"text/x-matlab"'.
   ...

This reminded me of changes I made to /usr/share/doc/packages/freedesktop.xml 
and possibly some other mime-related files. Reinstalling the package shared-
mime-info fixed the issue. However, using the command "mimetype" returned the 
correct mimetype and so did the properties dialog which can be accessed by 
right-clicking on the file in dolphin:

$ mimetype file.pdf.gz 
   file.pdf.gz: application/x-gzpdf
(Of course I checked that before reinstalling shared-mime-info.)

Thus, I still consider this to be strange behaviour of okular. In case I figure 
out why it determined the wrong mimetype, I'll submit another post as a 
follow-up.
