Geo: Failed to remove git config error

On a Web console, I attempted to run:

Geo::ProjectRegistry.dirty.find_each do |registry|
    Geo::ProjectSyncWorker.new.perform(registry.project_id, Time.now)
end

Occasionally, I hit this error, causing this task to stop:

Rugged::OSError: failed to read descriptor: No such file or directory

This seems like it's happening because another job does a sync and removes the existing git config file. However, there is an exclusive lease surrounding the project ID, so I wouldn't expect this to happen.
