It is indeed

data FileFilterFlags
= FileFilterFilename
| FileFilterUri
| FileFilterDisplayName
| FileFilterMimeType

but we forgot to export it from the module where it is defined. Sigh.

The only workaround is probably to use (toEnum 0), (toEnum 1),  
(toEnum 2) and (toEnum 4) to get the flags (note the powers of two).  
It'll be exported in the next release.

Sorry about the hassle, thanks for the report,
Axel.
