Banshee consuming 100% CPU after quitting

[Alex Peters]

I double-clicked an MP3 file to play it. Banshee opened. Preferring to play the file with Totem, I closed Banshee.

90 minutes later, top reports that Banshee never actually quit and has in fact been consuming near 100% CPU in the interim.

strace on the process says that Banshee is doing this repeatedly:

futex(0xe657c4, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 107807, {1316410606, 586000000}, ffffffff) = -1 ETIMEDOUT (Connection timed out)
futex(0xe65798, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0xe657c4, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 107809, {1316410606, 686000000}, ffffffff) = -1 ETIMEDOUT (Connection timed out)
futex(0xe65798, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0xe657c4, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 107811, {1316410606, 786000000}, ffffffff) = -1 ETIMEDOUT (Connection timed out)
futex(0xe65798, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0xe657c4, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 107813, {1316410606, 886000000}, ffffffff) = -1 ETIMEDOUT (Connection timed out)
futex(0xe65798, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0xe657c4, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 107815, {1316410606, 986000000}, ffffffff) = -1 ETIMEDOUT (Connection timed out)
futex(0xe65798, FUTEX_WAKE_PRIVATE, 1) = 0
