Fix bug #5968: Assertion while reading a document with multiple equation labels.

Browse Source 
This is another ad-hoc solution for the problem of a zero buffer pointer while reading a document or when using cut&paste.

This simple solution would be suitable for branch.

see also e.g. r29085, r28319, bug #5688.
