error with corrupted cache

[revolunet]

Digging deeper in source:

Error: unexpected end of file
    at Zlib.zlibOnError [as onerror] (node:zlib:189:17)
    at Zlib.callbackTrampoline (node:internal/async_hooks:130:17) {
  errno: -5,
  code: 'Z_BUF_ERROR'
    }

After a rm -rf ~/.kontinuous it works fine.

Should we add a try/catch here to make a more explicit error message ?
