Can't view my own comments

Is anyone else having this problem, with their own comments or even my own?

• FAIL: /comments?group_by=comment&search[creator_id]=13506
• FAIL: /comments?group_by=comment&search[creator_name]=RaisingK
• Fine: /comments.json?group_by=comment&search[creator_id]=13506

I checked my comments and a few other users' and I can view them fine, but I get failborus when I try to view yours.

This bug is due to expunged posts, which you seem to have a few comments on. I would have expected that comments on expunged posts are deleted, but it looks like they're not currently. (The reason the API works is because it doesn't need to load the non-existent thumbnail like the regular pages do.)
