The attached file contains the code that is generating the error, line 4
specifically is called out in the traceback, but if I comment this line out
I get the same error from the next line that is querying the database. If I
start a web2py shell, I can copy and paste the offending line into the
shell and it returns the expected results, also if I switch the database
back to sqlite everything works as expected.
