Cache ls throwing errors and crashing

I’m am trying out the new cache feature for the first time. I set up the cache remote directly on top of my Google Drive remote (not on the decrypted remote) and tried to do list the files. The first time I try the command, I get this:
2018/01/11 18:05:20 ERROR : vn15h4p6371nmpmjdlj3od94: error listing: directory not found
2018/01/11 18:05:20 Failed to ls: directory not found

Then, if I run the command a second time, I get a panic:
panic: runtime error: slice bounds out of range

I am using the latest beta: rclone-v1.39-023

I also tried it with v1.39 release.

Thanks for the help.

This is likely the same issue as https://github.com/ncw/rclone/issues/1961 (at least the traceback looks the same). Can you add your info to that issue please?
