Subject: StGIT fails to clean patch series, and to go to a patch

I have patch series with empty patch in the middle of the stack.
After trying to stg-clean (and failing) stack looks like below:

1167:[gitweb/web!git]$ stg series -e -s
+ gitweb-Always-set-from_file-to_file
+ gitweb-Add-status_str-diffinfo
+ gitweb-Easier-adding-parameters-to-current-URL
+ gitweb-Use-replay-to-generate-pagination
> gitweb-Use-replay-to-generate-alt-views
0 gitweb-Update-INSTALL-file
- gitweb-No-CGI_Carp-in-test
- gitweb-Test-config-override
- gitweb-Config-reader
- gitweb-Use-config-more

Now stg-rebase works, but stg-goto doesn't work. It returns
the following error.

1164:[gitweb/web!git]$ stg goto gitweb-Use-config-more
