Illegal attribute value when Unicaode enabled

I have PLSQL Developer, a Oracle 10 client and an Oracle 8I database.

When viewing a table (from the browser) I get an error "illegal attribute value"
Column information is not displayed, i.e. all columns are missing. Same thing happens when I switch to "single record view" for a record.

Now, this error does not occur when I disable "Perferences...Options...Unicode enabled"

It seems field information is fetched with some unicode flag, which leads to an "illegal attribute value" ?

Some of my collegues have the same problem, and some do not.
Must be a setting in the Oracle client, but what exacly I do no know. The Oracle 8 database does not support unicode.

Anyway, is seems odd that character settings should result in columns information not being fetched.
