Dictionary lookup

[kaia009]

Question:
A clear and concise statement of your question.
Foliate shuts down if I attempt to look up a word in dictionary. And the text-to-speech command is disabled.
Both dict. lookup and text-to-speech worked perfectly in 20.04.
I have installed sdcv and added the dictionaries - and lookup in terminal works perfectly.
I have installed Festival, added a festvox voice, etc.

Version:

• Foliate version: 2.6.4
• OS/Distribution and version: [e.g. Ubuntu 18.04] Ubuntu 22.04 (fresh install, not upgrade)
• Desktop environment: [e.g. GNOME 3.36] Gnome 42 and Wayland
• Installation method: [e.g. Flatpak] : ppa:apandada1/foliate

Update: I was going to ask whether this is a Wayland issue and realised I restart Ubuntu without Wayland - which I did.
The dictionary lookup was resolved, but the text-to-speech issue was not

New update: SOLVED
After restarting again in Wayland, BOTH dictionary lookup and Text-to-speech are working perfectly.

I have now installed Ubuntu 22.04 with freshly (i.e. reformating the partitions) on TWO - 2 - laptops.
a) In both cases dictionary lookup and text>speech did not initially work on the Wayland windowing system (which is now default on 22.04) although I restarted several times to be quite sure.
b) In both cases dictionary lookup and text>speech both worked perfectly when I restarted with the legacy windowing system. (reached if the user clicks the bottom-right wheel on the log-in page before entering pass phrase.)
c) Oddly, in both cases, dictionary lookup and text>speech both worked perfectly when I again restarted with the Wayland windowing system. Since that first detour to legacy, dictionary look-up and text>speech has worked without a glitch.
I should add that the character set of the epub book I was reading was not standard latin.

I think this is worth noting, since the "workaround" is so simple, it would be a pity if users were not informed of it.
So I am reopening the post.
