--- Comment #32 from Nicolas Fella <nicolas.fella at gmx.de> ---
Git commit 2f8825b489ecc69bed67a49abdcb643d1fa42b4a by Nicolas Fella.

Add null check for StorageAccess interface in storageAccessFromPath

In slotInterfacesRemoved we do a remove+add cycle

During that cycle the backend object is null, so querying the StorageAccess
interface will return null.

This means that when something calls storageAccessFromPath in reaction to
the removed signal we will get a null StorageAccess.

The overall design is a bit shaky here, but we can handle it more gracefully
by checking the result for null
