I tried modifying the test case for different selection mode for all LAFs. 
In case of FILES_AND_DIRECTORIES and DIRECTORIES_ONLY, the test passed in all LAFs.
But when the selection mode is set to FILES_ONLY, the UI in GTK doesn't show the file lists and test is failing.

However If I test manually for each selection mode,  the behavior is same for all LAFs.

1) In case of FILES_AND_DIRECTORIES, able to select single as well as multiple directories or files.
2) In case of DIRECTORIES_ONLY, able to select single as well as multiple directories but not files.
3) In case of FILES_ONLY, able to select single as well as multiple files but not directories.
