Sure. One thing I notice is that, [unknown files inside the idb directory would cause this error.](https://searchfox.org/mozilla-central/rev/581466eef9269afb03d8a0dba2f50215f3a9026c/dom/indexedDB/ActorsParent.cpp#16740) Also, even after we fix that, we probably want to collect more precise data (e.g. which function returns error inside the `GetDatabaseFilenames`) rather than only tracking the returning error for `GetDatabaseFilenames` (I assume this bug blocks bug 1594080 since that bug is going to ignoring this error for initialization).
