MPD+lastfmsubmitd: Clearing my playlist is killing lastmp

Question

Hey folks!
I'm sorry if this topic was already discussed, but i was not able to find it using the board search!
My setup: mpd with ncmpcpp as frontend. Due to some problems with mpdscribble I switched to lastfmsubmitd with lastmp as bridge.
Versions:
* mpd 0.15.12-1
* ncmpcpp 0.5.5-1
* lastfmsubmitd 1.0.6-1
When I clear my current playlist with 'c' in ncmpcpp, i get an error in /var/log/lastfm/lastmp.log and this deamon exits:
2010-09-21 22:09:39,419 lastmp[4035] ERROR: Aborting: Traceback (most recent call last):
File "/usr/bin/lastmp", line 237, in <module>
daemon(cli)
File "/usr/bin/lastmp", line 196, in daemon
mo.observe()
File "/usr/bin/lastmp", line 153, in observe
self.wake()
File "/usr/bin/lastmp", line 78, in wake
song = Song(self.mpd.do.currentsong())
File "/usr/bin/lastmp", line 29, in __init__
self.artist = getattr(sobj, 'artist', '')
File "/usr/lib/python2.6/site-packages/mpdclient2.py", line 270, in __getattr__
return self[attr]
KeyError: 'artist'
As you can imagine: it is quite annoying, if you clear your playlists and every further title is not submitted to last.fm due to this error... Does anyone know how to fix this problem?
Cheers and thanks!
Chris

Answer 1

In the meantime you can edit /usr/bin/lastmp and exchange the first few lines of class Song with the following snippet. Working fine for me and lastmp is surviving playlist clears.
class Song:
def __init__(self, sobj):
self.artist = ''
if hasattr(sobj, 'artist'):
self.artist = getattr(sobj, 'artist')
self.title = ''
if hasattr(sobj, 'title'):
self.title = getattr(sobj, 'title')
self.album = ''
if hasattr(sobj, 'album'):
self.album = getattr(sobj, 'album')
self.time = int(0)
if hasattr(sobj, 'time'):
self.length = int(getattr(sobj, 'time'))
self.file = ''
if hasattr(sobj, 'file'):
self.file = getattr(sobj, 'file')
I already wrote an email to the author with the suggested change but didn't get a reply so far.
