re-generate failed thumbnails

[David Prieto]

Binary package hint: nautilus

I have noticed that, when a thumbnail fails to be generated, the generic icon remains there forever unless you go and delete the ~/.thumbnails/fail folder. If you do, nautilus will try to generate it again.

Is there a reason for this not to be done automatically? Thanks.

thank you for your bug report, doing thumbnails take quite some ressources and there is no reason to retry again and again thumbnailing files which didn't work if they didn't change

That's the thing. Files aren't thumbnailed even if they change, like when they finished being downloaded with Transmission. Also, if you open a directory with videos before installing their necessary codecs you will get the generic icons, and installing the codecs afterwards will do no good.

Really, there are plenty of reasons to retry thumbnailing at least once in a while.

nautilus compares the image and thumbnail timestamp to update the thumbnail that should be working, there is already a bug about adding an option to manually retry the thumbnailing
