Android :: Why Would ImageView.setImageURI() Work In 2.2 But Not 2.1

I am displaying images and some text in a list view with an adapter. The images are pulled from the web, then cached locally and displayed. The images are already small (60px square), and I know their size, so I'm using the advice from here suggesting I use setImageURI instead of decoding the bitmap. The class that does the work is a modified version of Fedor's ImageLoader

The code attaches a stub drawable to the ImageView until the desired image is downloaded from the web, then loads the cached file from the sdcard. In Android 2.2 this works just fine. It's fast, and I don't get OOM crashes. On 2.1, though, I get the following error:

The ImageLoader class is as follows:
