Oh, what the hey, I'm up anyway.
Running from the command line (/usr/bin/python /usr/bin/software-center) gave something that might be of interest:
Start the review, console message was:

Close the window with the review failure, and got:

Just as a guess, the line about The name com.Gwibber.Accounts was not provided by any .service files looks to be indicative.
I'm guessing that the leading com. is some sort of a typo ... Maybe a space was left out?
