Bug Description

Ref. (a'k'a reopen) https://bugs.launchpad.net/hplip/+bug/1690516

HPLIP Version
```
HP Linux Imaging and Printing System (ver. 3.20.9)
HPLIP upgrade latest version ver. 1.0
```

Linux: Arch 1.4

Reproduce:

```
hp-align -i -l debug -d <device uri>
```
and after page printing it crashes with output described in the reference above.

In file /usr/share/hplip/base/maint.py
```
    if to_bytes_utf8("manual") in data:
        log.debug("Device supports manual calibration")
        data = status.StatusType10FetchUrl(func, "/Calibration/Session", "<cal:CalibrationState xmlns:cal=\\\"http://www.hp.com/schemas/imaging/con/cnx/markingagentcalibration/2009/04/08\\\" xmlns:dd=\\\"http://www.hp.com/schemas/imaging/con/dictionaries/1.0/\\\">Printing</cal:CalibrationState>")
        import string #
        data = string.split(data, "/Jobs")[1] # <=== S O M W H E R E H E R E
        data = string.split(data, "\r\n")[0] #
        data = "/Jobs" + data
        data = status.StatusType10FetchUrl(func, data)
        data = string.split(data, "Session/")[1]
        data = string.split(data, "<")[0]
        data = "/Calibration/Session/" + data + "/ManualSelectedPatterns.xml"
        global calibrationSession
        calibrationSession = data
        dev.close()
    return 0
```

That's all.

The solution, may be, that I used locally debugging the bug

```
    if to_bytes_utf8("manual") in data:
        log.debug("Device supports manual calibration")
        data = status.StatusType10FetchUrl(func, "/Calibration/Session", "<cal:CalibrationState xmlns:cal=\\\"http://www.hp.com/schemas/imaging/con/cnx/markingagentcalibration/2009/04/08\\\" xmlns:dd=\\\"http://www.hp.com/schemas/imaging/con/dictionaries/1.0/\\\">Printing</cal:CalibrationState>")
        log.debug("data:")
        log.debug(data)

        from email import message_from_string
        headers = message_from_string(str(data, 'ASCII').split('\r\n', 1)[1])
        location = headers['Location']
        log.debug("location:")
        log.debug(location)

        data = status.StatusType10FetchUrl(func, location)
        log.debug("StatusType10FetchUrl:")
        log.debug(data)
        data = data.split(b"Session/")[1]
        log.debug(data)
        data = data.split(b"<")[0]
        log.debug(data)
        data = b"/Calibration/Session/" + data + b"/ManualSelectedPatterns.xml"
        log.debug(data)
        global calibrationSession
        calibrationSession = data.decode("utf-8")
        dev.close()
```
