I searched a little and tried your topic Banshee isn't starting anymore, but I still had no success yet. So I will explain my problem shortly and then post the error-messages:

Both players worked fine until Rhythmbox suddenly crashed and didn't start any more. So I tried Banshee (they are both installed on my system) and it crashed after a few seconds while scanning for new media and doesn't start any more either. Both players can be started from other users, for example as sudo or at the guest-account. So there is possibly something wrong with the user, but I don't know what. So, thanks for your help!

Here are the error-messages:

Your Banshee error looks like something generated by bad configuration, would you try and post the contents inside your ~/.gconf/apps/banshee-1/player_window/%gconf.xml ? The error doesn't seem to be very related to the size of the window, but won't hurt trying. –  Wolter Hellmund Nov 6 '11 at 9:33

Run this in terminal:

sudo rm -rf /usr/share/rhythmbox/plugins/magnatune/
sudo rm -rf /usr/lib/rhythmbox/plugins/magnatune/

And try to launch Rhythmbox again!

This worked for me! –  Jonathan Nov 23 '11 at 2:06

If you are the only user who can't start the application, then I would bet the error is configuration related.

Backup your Rhythmbox and Banshee configuration and delete the original files, that might fix the problem.
