I'm having a problem using mylyn jira connector with jira 6.1

I have some queries configured, which work, but now I can't add a new query. I've tried adding the same query as a filter import and using the eclipse form.

In both cases I get the following error message, even though the query itself doesn't contain any percent characters:

Error in the JQL Query: The character '%' is a reserved JQL character. You must enclose it in a string or use the escape '\u0025' instead. (line 1, character 13)
