Very curious, no? What am I doing wrong here? Equally as weird -- my manifest:
<intent-filter
    android:icon='@drawable/ic_launcher'
        android:label='AndroidMHT File'
    android:priority='1'>
    <action android:name="android.intent.action.VIEW" />
    <action android:name="android.intent.action.EDIT" /> 
    <action android:name="android.intent.action.PICK" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data android:scheme="file" />
    <data android:scheme="content" />
    <data android:mimeType="*/*" />
    <data android:pathPattern=".*\\.mht" />
    <data android:host="*" />
</intent-filter>
