I had a similar error on my PRS-300 when trying to connect to it from Calibre while this custom software was installed, regardless of whether it was in Sony or ebookapp mode. I don't remember the exact error (it went away when I removed the software), but that looks familiar.
This is probably an issue that needs to be updated in Calibre, though ideally the new software shouldn't break syncing when running the Sony software.
