Default MMS not saving correctly with ALL third party apps, please help me test

The problem is that when i'm trying to save an MMS sent to me through a third party SMS app, it'll save the file as "null" or basically a file without the ".jpg" extension. When this happens the picture doesn't show up in any imaging viewing app. The only way to view it is to either attach the .jpg extension to it by renaming or by going into a file manager and "open as..."

When the file saved is 450-501KB, it'll save as null 75% of the time.
Anything higher or lower saves correctly 100% of the time.

To avoid this problem, I have to use Hangouts. It seems immune from this issue. Every other third party app, Chomp SMS, Handcent, Go SMS, Textra and Hello SMS has the problem.

I know for sure this issue happens on SlimKat ROM and AICP ROM with stock kernels and ElementalX/Franco kernels.

EDIT: Issue present on CarbonROM now too. Gonna test these ROMs again but with no apps installed other than the thirdy party app.
