Hi Patrick,

What happens if you do

$ h5ls <filename>

where <filename> is the file you're trying to open? This looks like it could be an error outside of yt.

Also, can you load() any other snapshots?

I stumbled over some error in yt while executing a script that used to work on an older version of yt. Here is the traceback:

I'd be very thankful if somebody got any idea how to fix this!
