Also happens for 0.1.5-1

[sjovdnbos]

The key shown in the error message is a false key and the result of wrong indexing and subsequent wrong error formatting.
I circumvented the issue by casting unicode to string before the pyrakoon client executes its type checking

Fixed in

#213

Package information:

openvstorage-extensions-0.5.3-dev.1551796013.5e25eee

Made pyrakoon ticket to solve underlying problem:
