167, Cannot open dictionary file eng_bul.dic or bul_eng.dic
It is looking for those files, but not finding them. They exist, so it must be looking in the wrong place.
I don't use KDE4, but in KDE3 I think you'd need to set the "workpath" to be /home/kode/
or maybe even
(because this is a windows program and the exe file is probably looking in it's own directory for the files).
Otherwise make a little script:
Make it executable:
chmod +x /path/to/script
And call that script from your menueditor with /path/to/script
