Hi David,
Thanks!
Your package searching is certainly better than mine: i had found the package kdesdk-scripts before, but not code-aster-gui nor anyremote-doc.
I've installed all 3 of them, but still get the same error message.
Also /usr/share/icons does not have a subdirectory crystalsvg although it does have a subdirectory gnome. (But maybe that's a red herring.)
Or maybe i have to install the kde desktop and use it at least once to get crystalsvg to work?
Anyhow, thanks for your help, any any other advice or suggestions.

A little update here: i installed task-kde-desktop --- all 1.9G ---
And if i run okular from a terminal on the Plasma desktop (as a different user), okular issues no warnings.
But when i switch back to xfce, and run okular from a terminal as my normal user, i still get the
Icon theme "crystalsvg" not found.
message.
So i suppose the kde terminal is set up with just the right environment variables or something.
Any clues are appreciated!! :)

(PS: sorry for top-posting in my previous reply, gmail really likes top-posting and i have to make a conscious effort to avoid it. Maybe there's someway to configure this also?)
