AttributeError: 'ResolveUIDView' object has no attribute 'uuid'

I have the following Error since yesterday on multiple times. I have no install an addon or upgrade the Plone Installation in the last days. Many Urls are affected. The Site hangs after some time. URLXXX is a Placeholder for the diffrent URLs. The System isPlone 4.3.10 as Zeo-Installation with 6 Clients and one ZeoServer on diffrent Machines. The Blobstorage is mounted via NFS in the Clients. In the event.log of the clients are message like:

ERROR Zope.SiteErrorLog 1480079607.450.897158190613 URLXXX/resolveuid
Traceback (innermost last):
   Module ZPublisher.Publish, line 138, in publish

   Module ZPublisher.Publish, line 48, in call_object
   Module plone.outputfilters.browser.resolveuid, line 62, in __call__
   AttributeError: 'ResolveUIDView' object has no attribute 'uuid'

The logfile of the Zeoserver is ok. Can anyone tell me what the error means?

/resolveuid/<uuid to object> are urls that should translate into full urls from content. If resolveuid is getting called without an actual uuid as part of the url, you maybe have some bad links. Check your content.

Also, it shouldn't affect the availability of your site--it is mostly a harmless error.

Maybe something else is going on.
