I may fool myself but could it be caused by an already gone slice 
data? It very looks like that only a specific string property is 
corrupted which got the same slice data as an input parameter.

I thought that the slice data should stay referenced in the 
persistent object anyway but the GC seems not so smart to detect 
this.

The error can be prevented with .dup so far.
