bulk creation of image gallery aliases broken

The problem of image/tid/# is covered in http://drupal.org/node/225002

A problem is described there, I did read it before creating this issue. What is reported here is that aliases are not created as per configuration. I could not see anything like that described in 225002.

Can you explain what steps you took for bulk generation?

I think I did. Here it is again:
- set "Pattern for all Image Galleries paths:" to "gallery/[catpath-raw]"
- selected "Bulk generate aliases for categories that are not aliased"
- submit the whole form
- message reported that no aliases were created, wrong, first bug
- not the expected aliases were created, second bug

The way that it now works is described in http://groups.drupal.org/node/6706#bulk_generation_new

Is that the method you followed?

The "How Bulk Generate differs from the old Bulk Update" section doesn't really give you a method to follow. It just tells you that new aliases are created in batches. What am I missing? Yes, I did delete existing aliases before trying a bulk create, if that's what you are asking.
