With some albums I am seeing several errors printed to the console window where picard is run when loading the album.  This happens using the plugin version installed by picard using the plugin setup in the configuration, which appears to be version 0.4.

Here is an example:

}}{{E: 00:53:08,733 /usr/lib/picard/picard/album.error_append:287: Traceback (most recent call last):
