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.
