Eu consegui resolver o problema, apesar de na minha opinião não fazer muito sentido. No arquivo AndroidManifest.xml eu precisei trocar o name da activity

<activity android:name=".ListActivity"></activity>

para:

<activity android:name="android.app.ListActivity"></activity>

e aqui vai o porque achei estranho: as outra duas activities que eu tenho no meu projeto estão na mesma pasta que essa. E no arquivo manifest elas estão setadas como:

<activity android:name=".PreferencesActivity"></activity>
<activity android:name=".MainActivity">

Dá mesma forma que esta estava, mas ao contrário desta, essas duas funcionam perfeitamente
