although the docs say you can substitute \\ with / in path names, one must use \\ in e32db.open()

i.e.

import e32db
e = e32db.Dbms()
e.open(u"c:\\database.db")
e.close()

will succeed but


import e32db
e = e32db.Dbms()
e.open(u"c:/database.db")
e.close()

will fail with SymbianError: KErrBadName
