Unusual behavior when Multi-threading is disabled

[Ashex]

When Multi-threading is disabled, htop stops working and crashes when you try to make a setting change. To replicate this, follow these steps:

1. In Instruments, go to Preferences and disable Hardware Multi-Threading.
2. Open htop, notice process information is not displayed.
3. Go into setup and change something, for example toggle tree view.
4. Hit done to save.

Deleting the settings file under ~/.config/htop does not fix anything, only turning multi-threading back on corrects the issue. Here is a screenshot of the unusual behavior:

OSX Version: Mountain Lion
htop Version: 0.8.2.2
Installed by: Macports
