Errors ... see below especially the "value" argument is out of bounds and Uncaught TypeError: Cannot read property 'slice' of undefined

The URL is https://dweb.me/arc/archive.org/details/hanabookstory?version=true
I also had a report of this page complaining about an invalid hash, but can't repeat that.
Note that https://dweb.me/arc/archive.org/details/commute?verbose=true works, so it seems to be specific to WT not handling errors for this specific file.

The exception is actually coming from videostream. Could you open an issue there?

[jhiesey]

Bug in videostream should be fixed. Closing this.
