rhythmbox freezes on start of song

[frEEk]

About 1s after starting a new song, rhythmbox uses 100% CPU (single core) and the UI freezes. Music continues to play fine. Thaws our after about one minute and interactions with GUI work fine until a new file is selected or starts automatically. Keyboard audio keys don't do anything during the freeze.

This behaviour started out of the blue. Only suspect package that updated before it started is libaudiofile1, but I backdated that and the problem still occurred.

Tried an strace but the machine froze. ltrace showed nothing obvious (to a non-linux dev like me anyway).

Playing files with Totem did not show this issue. Neither did SMPlayer

Ubuntu 14.04
Rhythmbox 3.0.2
amd64 binaries
Tested with MP3 files only

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

Aaand now the issue just went away. apt and dpkg not showing any updates since this report was filed.
I'm at a loss as to potential explanations. Machine was not under heavy load during the time the symptoms were investigated.

thanks, closing then, if it's not reproducible and lacks debug info it's not something that can be worked on
