This seems like a very strange error.
In trying to troubleshoot this further I looked at the structure of x. The
new x has the length of the Index (2001-01-05 = 11327).
> library(zoo)
> x = zoo(1:5, as.Date('2001-01-01')+1:5)
> str(x)
zoo series from 2001-01-02 to 2001-01-06
Data: int [1:5] 1 2 3 4 5
Index: Class 'Date' num [1:5] 11324 11325 11326 11327 11328
> x[as.Date('2001-01-05')]
2001-01-05
4
> x[as.Date('2001-01-05')] = 0
> x
Error in dimnames(x) <- dn :
length of 'dimnames' [1] not equal to array extent
> str(x)
zoo series from 2001-01-02 to 2001-01-06

Obviously this is hard for anyone to troubleshoot if you can't reproduce it.
I get the same error in R versions 12.0 and 13.0 (although I don't get the
"warning zoo was built under R 13.1" warning when I use zoo in R 12.0)
