librsvg: missing corpus links on fuzzer statistics page

[correctmost]

Description

Project: librsvg Fuzzer: libFuzzer_librsvg_render_document

The links in the "corpus_size" and "corpus_backup" columns have not been present since Aug 12, 2024:

Here's what I see in the bucket:

Observations

• Recent uploads are missing a MIME type
• There are gaps without corresponding build failures for those days
• latest.zip seems to be pointing to the file from Aug 12
• public.zip seems to be pointing to the file from Jun 27 (despite the Sep 24 timestamp)

Other notes

• I committed a change to the project on Aug 12 (https://github.com/google/oss-fuzz/pull/12331), but I'm not sure how it could affect corpus uploads
• Regular builds and coverage builds are passing
• #12524 seems similar in nature
