App Crash when you tap "Log out of Dropbox"

[ginatrapani]

I can't reproduce this in the simulator, only on my device (an iPad). But I can reproduce it on the device reliably. When logged into Dropbox and browsing a todo.txt list, go to Settings and tap "Log out of Dropbox" and the app freezes and crashes. Here's the stacktrace:

After uploading the latest build to TestFlight, uninstalling the app completely and reinstalling, I can no longer reproduce this problem on my device. Cautiously closing for now, unless we're able to reliably repro on a totally clean new install.
