All index entries are "Unknown application"
After an f-droid client update some time ago all applications are shown as "Unknown Application" and couldn't be installed, updated or deleted. Reinstalling and deleting app data from sdcard doesn't help - after repository sync everything is again "unknown".
The device is android 2.1. Logcat doesn't show any useful info.
Sorry for bad photo quality - ddms makes corrupted screenshot for some reason.
