I just had this occur (TAREXIT_FAILURE on a removed deep directory) on a
system that was already running 1.22.90-owl1, confirming that it is
indeed still affected.

Are you going to propose a patch for this, or should I?

tar: ./home/clients/websites/w_client/drupal/5.10/cache/example.org/0/group: 
Cannot savedir: No such file or directory
tar: ./home/clients/websites/w_client/drupal/5.10/cache/example.org/0/group: 
Directory removed before we read it
tar: ./home/clients/websites/w_client/drupal/5.10/cache/example.org/0/solution:

Thanks,
