No, weston_output_destroy() already frees the string, so this would
cause a double-free failure on program termination. E.g.:
*** Error in `./weston': double free or corruption (fasttop): 0x00000000016cb1e0 ***

I don't know what the name gets used for so am reticent to remove it.
But I think the code is all okay as is.

Thanks for your review, hope you don't mind if I take the R-b
without the requested change.
