sa-update error

Since today sa-update (without any parameters) suddenly gives this response:

Code:

---

config: invalid regexp for rule __PDS_FROM_2_EMAILS: /^\W+([\w+.-]+\@[\w.-]+\.\w\w++)(?:[^\n\w<]{0,80})?<(?!\1)[^\n\s]*\@/i: Nested quantifiers in regex; marked by <-- HERE in m/(?i)^\W+([\w+.-]+\@[\w.-]+\.\w\w++ <-- HERE )(?:[^\n\w<]{0,80})?<(?!\1)[^\n\s]*\@/



channel: lint check of update failed, channel failed

---

Any ideas?
