Endless boot loop when adjusting automatic backlight settings

[GoogleCodeExporter]

What steps will reproduce the problem?
--------------------------------------

- Visit System Settings > Display > Automatic Backlight
- Set up as follows:

Enabled: checked
Window length: 2s
Reset Threshold: 40lux
Sample Interval: 2s
Use Custom: checked
Allow light decrease: checked
Decrease hysteresis: 0%

Repeatedly change window length to a value between 5s and 2s. After each 
change, uncheck Enabled then recheck (values only apply after doing reenabling).

What is the expected output? What do you see instead?
-----------------------------------------------------

Phone will eventually reset to Jellytime boot animation. Animation plays, gets 
brighter for an instant then darker and repeats. Requires battery to be pulled.

Wiping cache/Dalvik cache and Reflashing Jellytime via recovery results in 
phone booting and arriving at upgrading apps dialog. After this is complete, 
handset returns to infinite boot screen animation.

Restoring a full backup from CWM solves the issue.

What version of the product are you using? On what operating system?

Please provide any additional information below.
------------------------------------------------

Doesn't always crash instantly. Around 1/20 times of unchecking/rechecking 
'Enabled'.

Have managed to successfully recreate the problem about 10 times now in r10.2, 
r12 and r15. Didn't test the other builds.

Attached logcat contains events from adjusting the brightness as per above 
steps, followed through to bootloop. 

I believe the crash took place at around line #5721:

W/Adreno200-ES20( 6711): <__load_uniform_matrix:815>: GL_INVALID_OPERATION
E/GLUtils ( 6711): GL ERROR - after deleteUnusedTextures() glError (0x502)

Have you tried installing then clear dalvich/cache after it installs? Before 
you get to boot screen?
