Could they have been imported from different modules?
Some graphics libraries do things like this:
module Bar where
import qualified Foo
data Event = ... something involving Foo.Event ...
...
meaning that there are two incompatible Event types around, which will
look the same in error messages which don't show fully qualified
names.
