Just installed a brand new snapshot, with a brand new database.

After making a post, then editing that post or making any other posts.
This error is shown at the top of the header on that topic and on the viewforum.php

It seems to be an encoding issue, some topics display fine but with the header error, other topics show only encoded text... i.e. [quote]gŸßž¯Ÿ·‚àxrLþñfòî-ø}2Q4×Üp™S'ï=â¥ÆûA0ŸÏýù¶/Õ,˜ü\á^$®†=Ó ô“xãöÈ2¼ÊD®Ã[¶ìíí9j$\…ž0ÊR1šŒÛíQÆ%HÖcßK~z±Ì ËMÏ, æ‘ê-ô»2
