--- Comment #3 from Jeremy Whiting <jpwhiting at kde.org> ---
That looks like spd_list_voices is taking a while. I'm willing to bet money
they have speech-dispatcher configured to use espeak or espeak-ng which in some
recent versions of speech-dispatcher give a way longer list than it should.
Setting it up with espeak-ng here on arch and running spd-say -L to give the
list of voices on the command line takes a couple of seconds and gives a list
of 13363 different voices... (because it's including all locales and some
mbrola variants, etc.)

Unfortunately there's not really a gui to configure speech-dispatcher yet.
Users that hit this can edit their configuration files in
~/.config/speech-dispatcher/speechd.conf to disable espeak and other
problematic synthesizers that have this issue. Or alternatively run spd-conf
and choose a default synthesizer such as flite or festival or pico that each
only have a few voices.

Alternatively I'll take a look and see if we can avoid that call in okular
until the user asks for the Accessibility page maybe, though that would slow
down switching to that page from other pages.
