Thanks for the bug report! I'll take a look at it this evening.

What ROM is this from?

I'm not sure. I just got the files fm a friend who asked my help to tweak some 
of the smali scripts. But I have attached the apk for your testing purposes.

Is there any chance that your friend modified the method it's crashing on 
before giving it to you? I haven't looked at the apk yet, but my guess is that 
this is a problem with the apk itself.

I'm not sure. The file decompile almost all correctly except for those few 
smalis which gives those errors.

There is definitely some weirdness with that apk. The debug information for the 
methods that it is erroring on is invalid, and makes no sense. The best you can 
do in this case is to use the -b option to turn off debug info.
