$ gsutil du -sh gs://test123/

CommandException: Cloud folder gs://test123/testfile[1994]/ contains a wildcard; gsutil does not currently support objects with wildcards in their name.

I'm unable to list the directory, or rename the folder. What should I do?

Since there isn't any answers here whatsoever, I'll post what I've done. I haven't put any effort into making this easy to use. YMMV.

Go back to commit d153cb33bfa8e96a32b2ebdee86e03251cfb71fd, which is where I was working at.
Revert commit 46c09952d137e8704c1209bb8bdfbb2e73a2cd5d after reading the commit message and making sure you're aware of why this was blocked.
Apply the patch at the bottom of this message. It effectively disables [ and ] as wildcard characters.

I've also filed a bug against gsutil to reintroduce support.

Here's the patch:
