Not sure if it’s a coincidence, but ever since my pull request was merged this morning (#44 Fill Background Path), I’m getting this error when I go to Window > Plugin Manager:
The operation couldn’t be completed. (Problem parsing repository source error 123.)
Apologies if I fat-fingered something…
The double quotes in your description needed to be escaped. Running
plutil -lint on the file to check for syntax errors would have caught that. I submitted a pull request that fixes it and adds a note about using plutil to verify the file. When @GeorgSeifert merges in the change, the Plugin Manager should work again.
Thanks! Now it seems obvious. Will definitely use plutil in the future.
If you use TextMate, you can use the “Bundles > Property List > Validate” command.
