I was able to reproduce it by creating that table and trying to insert a db_pretty_name with a string length of >4000 characters. But this breaks both the old and new driver. But they said that is works fine with 2.7. I'll try installing OpenACS and see if I can reproduce it and go from there.
Looking at the original error, is maybe the lob code being activated for this table, which probably doesn't have a lob column? The error says Oracle can only bind a long value for insert into a long column. Maybe a switch is messed up in the installer?
