GNOME Bugzilla – Bug 151080
does not generate thumbnail for new image with same name as old
Last modified: 2021-06-18 15:13:21 UTC
This problem shows up a lot for me because I use two different memory cards with my camera. When the first card is mounted, the correct thumbnails are generated, however if I unmount then mount a new card often many of the pictures from the old card will appear in the thumbnails, because there will often be files of the same name on each card even though they are different pictures. Nautilus should recognize that these aren't the same photos because they contain different data and regenerate the thumbnails. Perhaps having someway in the interface to do this manually would also help (a refresh doesn't work).
I get the same problem. After buying a brand new card, i put it into my camera and take some shots. I plugged my camera into my pc and old thumbnails from Chrismas appears. When I dbl click on the picture, the picture is correct. I f close & reopen the Nautilus window, the thumbnails are correct then.
Thanks for your bug report! What Nautlus version are you using? Is this still reproducible with Nautilus 2.10 or 2.11?
I tried the 2.10 LiveCD and it appears to be fixed however, it should probably be checked against a computer with 2.8 or 2.10 actually installed.
We didn't have any bug report on this issue for months. Closing. Feel free to reopen if it still happens.

Someone duplicated with 2.14.x, reopening. Also, bug 330555 (using 2.10.x) looks like it may be a duplicate.
Created attachment 67101 [details] screenshot displaying the problem
I am using just one card for my Konica Minolta and hit the bug too. (see attached screenshot) This is very annoying behavior. Is there some workaround available ? Is anyone working on this bug ? Can someone change the status of this bug ?
We detect modifications to images according to the thumbnail spec [1]. I suppose the mtime of the image is identical to the previous image's mtime, so gnome_thumbnail_is_valid returns TRUE although the image on disk refers to another image. [1] http://jens.triq.net/thumbnail-spec/modifications.html
The mtime checking is clearly not sufficient. I am willing to provide more data in order to debug and fix this - just tell what should I do.

Does this still happen to anyone with a recent version of gnome (2.18 or higher)? Can we close this bug? - Mike
I can confirm that this problem still exists in Nautilus v.2.20.0 Is there any workaround for this at this time? It's a fairly significant bug, at least to me anyway.
Increasing priority because this is 3+ years old bug and there is still no change.
Why are images being generated with identical names AND mtimes? Personally, I would like to see file size used as an optional comparison (in addition to the mandatory mtime comparison) to determine thumbnail validity, but there did not seem to be much enthusiasm for this idea on the freedesktop mail list. - Mike

> "Why are images being generated with identical names AND mtimes?" The example I have here is a digital camera with a broken clock that creates all files with a timestamp of Wed 31 Dec 2003 23:00:00 GMT. Pressing ctrl-R might be a good way for the user to hint that a more detailed comparison of images/thumbnails is desired?
GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org. As part of that, we are mass-closing older open tickets in bugzilla.gnome.org which have not seen updates for a longer time (resources are unfortunately quite limited so not every ticket can get handled). If you can still reproduce the situation described in this ticket in a recent and supported software version of Files (nautilus), then please follow https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines and create a new ticket at https://gitlab.gnome.org/GNOME/nautilus/-/issues/ Thank you for your understanding and your help.
