Error: could not delete files in a folder which is not synced

I set .* in the IGNORE LIST for not syc’ing dot folders. However, deleting the following toDelete folder results in an error message Could not delete/…/toDelete/.git/objects/pack`.

…/
toDelete/
.git/
/objects
pack/

How do I remove the error message?

@yltang: Apologies for the trouble. As a workaround please try deleting the ignored folder manually then retry the operation.
