Uploading certains images doesn't work. Looks like it's related to exif informations

Hello!

I found a very weird bug on EB5. It's something that was already happening on EB3.9, but it's more problematic with EB5. Let me bring some context.

I make a lot of articles, and use a lot of images. Sometimes, I use my own reflex to get some pics, especially when it's about conventions. No problem, I get those pic, but when I try to upload them on Easyblog, I have a bug with some pics. After further investigations, here is when the bug happen :

1) The image must have a ratio higher than 1 (Like 16/9)
2) AND The image has exif informations
3) AND The image is uploaded on EB, no matter what you use (Media manager, block, etc...)

On Easyblog 3.9, when I tried to do it with those conditions, I was getting an error while uploading: "Can't parse server response". However, If I saved the article as a draft, then went back on it, pics would appears on the media manager. The same thing happens on Easyblog 5, though, since I use blocks that don't allow to select an image on the media manager, if the uploads fails, I'm fucked

So, since the problem was happening only with pics I took with my reflex, I tried to see what those pics had that other pics didn't have. Since my reflex use EXIF informations to add some details on the properties of the image, I took a look on it, and tried to remove them, then upload again. The bug didn't happen. It means something on those EXIF informations seems to make this problem happening.

Now, some details. Here is a comparison of 3 files (Properties of those pics). On the left, the image making the bug happening. On the center, another image took with my reflex, but with a ratio lower than 1, so, not making the bug happening. On the right, the same image than on the left, but with exif information removed using the link on the bottom of the windows :





I also uploaded those 3 images (In the same order), to let you look at those pics, and maybe find what's causing this problem.

To reproduce the bug on EB5 (With composer):
1) Create a new article
2) Add a "thumbnails" block
3) Select a "problematic" file (here it's the 585.jpg)
4) The animation with the circle appears to show the pic is getting uploaded
5) You can't wait for a long time, the pic will never appears
6) [Optional] Save the article for later (draft)
7) [Optional] Get back on the article
8) [Optional] Click on "add media", and select "this post". The pics that didn't appear before was in fact properly uploaded, but didn't appear on the block.

To reproduce the bug on EB3.9 :
1) Create a new article
2) Add a media on the article using the media manager
3) Drag and drop the pic on the media manager (585.jpg)
4) The pic is uploaded, but you'll get an error saying "can't parse server response"
5) Go back to the navigation on the folder you tried to upload the file. It won't appear.
6) [Optional] Save the article as draft
7) [Optional] Get back on the article
8) [Optional] Try to add a media, and browse the file on the folder where you tried to upload the pic before. It now appears properly, and you can insert it on the article without any other problem.

On EB3.9, it wasn't really a problem. I mean, It's not a hard thing to save as draft then going back on the article. But on EB5, some block won't let you choose a file using the media manager, and you have to upload them. So, if the upload fails, well... It'll be hard to do something

I know it's not a bug easy to reproduce, so, feel free to ask me more details. I also can understand that because of how hard it is to reproduce this bug, you won't priorize a fix or even make one. Since I know how to fix the problem now, I can deal with it anyway. But I hope it's a very isolated case
