@iterati: Just to make it perfectly clear:
* what's the last working version on your device?
* what's the first broken version on your device?
(So we can better figure out which sets of commits might have introduced the regression, and why).
EDIT: Also, a log of the crash would be mightily helpful.
EDITē: Which you should be able to get over ADB via
Code:
adb logcat 'luajit-launcher:D KOReader:D *:S'
according to our doc
