Occasional error in FeedProcessor.js

[Marc K.]

Binary package hint: firefox-3.0

In the Error console this error occasionally appears. I am doing a lot of javascript programming and always have the Error console display everything. The strange thing is that I haven't seen this error appear before.

Me too - in v.3.5.8 - no extensions or addons (that I know of)

Only one window open (+debug console) relatively light JS (no XML)
- very strange
