Uncaught TypeError: Cannot read property 'toLowerCase' of undefined #77

Can't reproduce it again but when I've typed in my style this appeared:

At /home/miga/.atom/packages/appcelerator-titanium/lib/utils.js:202

It is still 1.0.2 since its currently not showing me the 1.0.3 update.

It seems to be related to resolving auto-completions for class properties. The error suggests that the str2 has no characters, so accessing it via str2[0] returns undefined, and toLowerCase causes the final error. I can see that we added guards for str2, so this is not likely to happen again. If it does, please feel free to reopen!
