[Plugin: Theme Test Drive] crashes on php 5.3

had this plugin installed and used to work just fine – I was happy I found a way to work on a new theme while not having to brake the “live” one.

now my host upgraded to php 5.3 and the plugin stopped working – I mean, it now fully crashes the whole site (blank screen, you know …)

the only way to get the site working again is deleting this plugin over ftp.

Anyone with a solution to get this working under the new php version?

Thanks
