Title:
Failed thumbnail check not working properly
Status in GNOME Desktop Common Files:
New
Status in nautilus package in Ubuntu:
New
Bug description:
This is related to the gnome-thumbnailer code which is part of
Nautilus. However, I don't know enough about programming to fix it
myself.
If a failed thumbnail exists for a file, or specifically a universal
resource identifier, Nautilus will not try to create a valid thumbnail
for it, unless a non-failed thumbnail also exists for that URI/path.
Steps to replicate:
1) Create a new, blank document named image.jpg
2) make sure the failed thumbnail has been created, such as by restarting
nautilus with 'nautilus --quit'
3) navigate back to that folder, rename or delete the blank file, and rename
another image to image.jpg.
Result: no thumbnail will be created for the image.
When I was checking the thumbnail code for an unrelated issue (256x256
thumbnails take up too much space as PNG, sometimes larger than
original file), I also saw enough to be able to investigate this issue
a little. In the code for Nautilus, or gnome-thumbnailer, that I
looked at, it appeared that the code was doing a check to see if the
failed thumbnail was valid.
That is, if the modification time of the file as recorded in the PNG
Chunk data does not match, it probably shouldn't count as a match for
the file. But either it is incorrectly matching, or something else is
wrong.
While testing for an unrelated issue that seemed like it might no
longer exist, I found that as Firefox saves an item by creating a
placeholder and then saving the actual file using a .part suffix
(unless changed in options probably), it leads to this bug.
