Rhythmbox crashes on startup

[rubinstein]

After the update yesterday 20050322 rhythmbox (hoary) crashes when starting.
terminal-output:
ph@ubuntu:~$ rhythmbox

Rhythmbox-ERROR **: file rb-ipod-source.c: line 478 (rb_ipod_get_itunesdb_path):
assertion failed: (mount_point != NULL)
aborting...

can you get a backtrace of the crash (you can find one in the dialog to send the
bug upstream) ? Do you have an ipod ?

[rubinstein (rubinstein)]

I don't have an ipod - I wish I had one :-)

bug-buddy says:

do you know how to rebuild a debug version of the package
(http://www.ubuntulinux.org/wiki/DebuggingProgramCrash/) ? I can build a debug
package and upload it somewhere if needed.

[Tom R (tommy21)]

I experienced the same error after that update. I found the cause of this error
to be a mounted blank disc. As soon as i unmounted it, Rhythmbox would start again.

So in my case the bug would be "rhythmbox crashed at startup when blank writable
disc is mounted."

[rubinstein (rubinstein)]

Tom is right; Today the bug wasn't reproducible until I put a blank CD-R in - I
also had one in yesterday when starting rhythmbox.

This also happens when there is an audio cd in the drive.
