Gallery app does not refresh thumbnails correctly

[Richard Huddie]

PRE-REQUISITE:
Delete all images from the gallery

TEST CASE:
1. Take a photo using the camera app
2. Load the gallery app and view the thumbnail of the image just taken
3. Select the thumbnail and delete it from gallery (gallery should be blank)
4. Switch back to camera app, leaving gallery running
5. Take another photo using the camera (take it of something different to the first image)
6. Switch back to the gallery app

EXPECTED RESULT:
The new image thumbnail should be displayed in the gallery

ACTUAL RESULT:
The old thumbnail image from the first image is displayed. When you press the thumbnail the new image loads.

Thanks for your report. I confirm this defect with the steps in the description.

This also happens with the gallery populated with previous photos.
Seems to depend on both apps staying open.
Only seems to happen on the first photo.
Restarting the gallery shows the correct thumbnail.

Photo naming algorithm is part of qtubuntu-camera, file storagemanager.cpp: StorageManager::nextMediaFileName(). I believe that should be fixed to use a fixed counter ideally, or adding a timestamp.

[Florian Boucault (fboucault)]

A patch like that on qtubuntu-camera may do the job: http://pastebin.ubuntu.com/8253546/
Thinking of the better fixed counter solution and how to store the counter.

[Florian Boucault (fboucault)]

Side note: the best solution would be of course that the thumbnailer notices that even though the file name is the same, the file is different and therefore a new thumbnail needs to be generated.

This bug was fixed in the package qtubuntu-camera - 0.3.3+14.10.20140911-0ubuntu1

  * Prevent filenames from reoccurring when a photo is deleted and re-
    taken the same day, by adding time up to the second to the filename.
