Showing help inside demo crashes program

[gradha]

Just grabbed a copy of DCIntrospect. I tried compiling the demo example and run it on Xcode 4.0.2 with the iPhone 4.3 simulator. The example shows and I press the space bar to enter the introspection mode. Everything seems to work fine, but pressing ? to show the help screen crashes the application. The crash sometimes happens immediately, other times it seems to take a few seconds to trigger, but the backtrace is always the same:

#0  0x00000000 in ?? ()

This crash will be fixed once #19 is pulled.
