Extracting from test.rar

don@t43:~/test$ file-roller test.rar

But then file-roller gives:
"CRC failed in the encrypted file /home/don/test/test.rar. Corrupt file or
wrong password."
The window to enter a password never comes up.

Using file roller to create a password protected .rar works, but trying to
extract from it fails with the same message.
