Bug 507276

SUMMARY
I process lots of files  in a folder, output them in another and delete processed originals. But if I do it without closing the application, when I try to add the new clip, file selection dialog box doesn't automatically refresh the folder content and shows the deleted files too unless manually press the F5 button to refresh. Even if I change the folder and turn back the original folders it doesn't refresh automatically unless manually refreshed. Moreover, after the first launch of the app, even without opening the add file dialog before, if some files deleted after the launching of the application, file dialog still shows the deleted files when opened first time. It seems like application caches folder contents and doesn't update unless manually refreshed.

STEPS TO REPRODUCE
1. Open Kdenlive
2. Delete files in the (default) folder where previously used folder.
3. Open add clip dialog.

OBSERVED RESULT
Deleted files are still shown there until refreshed manually

EXPECTED RESULT
Open file dialog windows should automatically refresh and shouldn't show previously deleted files.
