in version 3.0.1 in Wheezy fully up to date as of ten minutes ago.
It seems to partially crash the thumbnail process, after a video file
(the thumbnail for which is a black rectangle) the page is blank white,
but if you scroll down after a while the thumbnails start again, then if
you scroll back up some of the previously failed thumbnails fill in,
some completely some only partially. I can produce a screen grab if you
like, where should I send it?
My phone camera produced file names of the format yyyymmdd_hhmmss.jpg or
.mp4 so with the exception of by file size it doesn't matter how I sort
them the video files are interspersed in the thumbs and it always fails
on the videos, the only way to get it to work is to filter videos out.
My Cannon camera produces image files of the format IMG_NNNN.JPG and
video files like MVI_NNNN_MOV where N is a sequential number, if I sort
bu file modification date so the video files are dotted about I get the
same behavior, if I sort by file name so the videos are at the bottom
the photo thumbs all load but it fails when it gets to the first video.
