Messages.app crashing. Not just any normal crash =(

Hi guys, I'll just get straight to the point here...

- iPhone 4 GSM, iOS 5.1.1, using latest untethered JB (Absinthe)
- All Cydia tweaks are updated to the latest
- Tweaks using are SBSettings, Zephyr, iFile, PDAnet, Activator



**When my messages.app crashes..........**

- A weird RANDOM color overlay (of around 30% transparency) will color the entire screen for ~1 second
- Then it will reboot completely. Loading icon, apple logo, boot up
- The color overlay is very weird, it is AS IF the screen/GPU has defects, which it does not
- The color is random, and pattern is random, sometimes its stripes, sometimes just a single color, sometimes multiple colors like rainbows, basically, the color is ALWAYS random


**What causes the crash.........**

- Minimizing the messages.app. This includes pressing home button or switching to a different app using task-switcher or by notification centre
- Deleting an entire threaded message
- Deleting a single message entry in a thread
- Tapping 'RETRY' (after tapping on red exclamation mark) when an iMessage fails to send
- Sleeping the phone when messages.app is in foreground (This will turn off the phone, not reboot. I will need to hold the power btn to start the phone)



I have tried to enter Safe Mode using SBSettings but it doesn't seem to work. When the phone resprings, it does not go into Safe Mode at all. All my tweaks still function and problem persists

I tried disabling Mobile Substrate during boot and problem still persists. Also, when my Mobile Substrate is disabled, all my tweaks don't work, except SBSettings. Shouldn't SBSettings also be disabled?

Tweaks as mentioned above, no other tweaks that mess with messages
I don't have iphonedelivery, never installed before

All other apps & tweaks are working fine, I doubt its any hardware defect.


I don't have a photo of the color problem but I'm trying to get it...
But just in case, this is how it looks like

Also, I've tried removing almost every tweak including Mobile Substrate but it still doesn't solve the problem...
Sigh

This are ALL my tweaks left

Restoring would only be my last resort

Thanks for reading
