AuroraStore doesn't show installed apps and updates

The list of installed apps and apps with update is empty.

In the system log I found, that there's an exception in CertUtil.java:57. This leaves the slot in certs[i] null. The access in CertUtil.java:71 leads to a null-Dereference.

Disabling Filter F-Droid apps in the settings helps and the apps are show. With the filtering, the list is empty.
