[TYPO3-v4] What is happening with id 0?

[Steffen Kamper]

Hi,

since some days i'm first time confronted with this exception, also 
wonder about the wording:

Uncaught TYPO3 Exception
#1222808333: Only strings can be digested by the StringCache. Thanks.

t3lib_cache_frontend_StringFrontend::set("ca01485af4c4ce3ba5c451435912d9bf", 
array, array, 86400)

This happens when calling any not existing id, in view module or in FE
domain/index.php?id=0

Anyone confirm this? Anyone examined already?
