Hi Fred, thank you for taking the time to help diagnose this!

> On subsequent runs you see the corresponding FAILED PREVIOUSLY
responses. Since there about 400 artists and 600 albums the behaviour
seems reasonable assuming the backend server was not responding in time
to all requests.

Hmmm… We rate-limit the requests we send to the remote server such that
there are never more than two requests in progress concurrently. So,
nothing should ever time out at the HTTP level unless the server truly
didn't respond. (We will not mistake a long wait time before we can send
a request for a timeout.)

At any rate, the FAILED PREVIOUSLY log entries indicate that this was a
genuine authoritative "no artwork available" response. Most likely, some
of your songs are for artists and/or albums for which the remote server
has no artwork. You can verify this by using curl:

curl "https://dash.ubuntu.com/musicproxy/v1/album-
art?artist=nosuchartist&album=nosuchalbum&key=0f450aa882a6125ebcbfb3d7f7aa25bc"
>/tmp/out

Replace "nosuchartist" and "nosuchalbum" with the (percent-escaped)
details.

If you have a thumbnailer crash, I'd be keen to get my hands on it. Is
there anything in /var/crash?

Not sure what's going on with the music app. It might be an unrelated
issue.

The thumbnailer will not ever purge its cache, unless it detects
database corruption, in which case it reinitialises the DB. But you
would see definite trace in the log for that.

I'm afraid that the best way for us to move this forward would be for us
to get our hands on your music collection. I'm looking at ways to create
artificial test data for such stress testing too, but it's going to be
tedious, and I want to make sure that we are getting a reproducible test
case.

Could you drop me a line at michi.henning@xxxxxxxxxxxxx please? I'd love
to get a copy of your flash card so we can nail this bug. Of course,
I'll reimburse you for the cost.

Cheers,

Michi.

Title:
  No thumbnails generated for OGG audio

Status in music-app package in Ubuntu:
  New
Status in thumbnailer package in Ubuntu:
  New

Bug description:
  Setup:
    Core Music app 
    BQ HD5
    OTA-7 15.04 r6
    Large collection of audio files in .ogg and .mp3 format on SD card
    Audio files tagged with Artist, Album titile, Track title etc.

  Expected result:
    Album covers and Artist images are displayed in Music app

  Actual result:
    Only mp3 audio files generate thumbnails. No Album of Artist thumbnails are generated for any OGG files

  To test the situation I have
  a) Cleared the thumbnailer failure cache
  b) removed the whole thumbnail cache directory
  c) Removed and reinsterted the SD card
  d) Uninstallled and reinstalled the core Music app

  Before the OTA-7 upgrade the thumbnails were shown for .ogg and .mp3
  files
