My initial suspicion is that this is a corrupted dex file. Does the apk/dex 
file actually work? Is it able to be loaded on a device?

Yes, this apk file actually works. It is able to be loaded on a device.

I was able to find an apk that causes this error message. This uses a style of 
obfuscation where they throw in unused "crap" classes that are malformed in 
various ways, but are never actually used/referenced. baksmali handles this by 
logging an error and skipping the class. Since these classes are never actually 
referenced, so they can safely be ignored/skipped.

In particular, if the class was ever actually referenced, dalvik would reject 
it during verification, so it could never actually be used.

So you suspect that I am getting this error because there is a class that is 
malformed in some way?

Yes. And in fact, I would be willing to bet that the "leaf" part of the class 
name with the error is "a" :)
