Errors with 'unserialize' while exporting the database

Hi Brad,

Great plugin, been using it over 1-2 now and works like magic.

I came across a site that is very large and the error settings on the server are slightly different, wanted to see if you know the cause of this error:

ERRNO: 8

TEXT: unserialize() [function.unserialize]: Error at offset 0 of 4 bytes 

LOCATION: /public_html/blog/wp-content/plugins/wp-migrate-db/wp-migrate-db.php, line 625, at January 22, 2014, 3:57 pm

Showing backtrace:

unserialize("icms") # line  625, file: /public_html/blog/wp-content/plugins/wp-migrate-db/wp-migrate-db.php
WP_Migrate_DB.recursive_unserialize_replace("icms") # line  584, file: /public_html/blog/wp-content/plugins/wp-migrate-db/wp-migrate-db.php
WP_Migrate_DB.backup_table("icms_events") # line  688, file: /public_html/blog/wp-content/plugins/wp-migrate-db/wp-migrate-db.php

Thanks for looking into this.

Mr Alexander
