File Gallery is broken

• Bug

This may overlap with the Bug report that "large file galleries are broken".

I consider mine not to be large, but it's broken anyhow. I first noticed it a month ago, when there were about 30-50 images in the file gallery. An image I knew I uploaded was not to be found anywhere. Back then, I thought it might be my mistake, and uploaded again, everything seemed fine.

But now there are precisely 300 images in the file gallery, and I wanted to upload a newer high-res version of an image I had uploaded last month. Then I had only a very low res version, but I had uploaded it as a stub, and created a Wiki page containing this image.

I could not find the image in the gallery! But the Wiki page containing it looked fine... So it was definitely in there, but was not to be found. Then I looked up the images ID in the page source, and used the search function of file gallery to find it - and there it was.

By the way: A feature request. The search function works, but it does NOT indicated WHERE a file was found. That is not very useful...

Then I uploaded the new high-res version, the Wiki page promptly showed it, everything looked fine again

Edit: there weren't 238 images vanishing from display, as I wrote in the first version of the bug report. That was my mistake: 238 of 300 images are in one folder, and 62 in another. That is still being displayed correctly.
But the issue remains that sometimes single images vanish from display, and can only be found again using the search function.
