Thanks for your report. I think the issue is that dask cannot correctly infer the dtype of the result - or at least not it's length (maybe because it does not do value-based casting? not sure).

As a workaround you could do an intermediate cast to an object:

python dac.astype(object).str.cat(dac, sep='--').astype("U").compute()
