[wp-testers] Problem with automatic upgrade

[Eric Smith]

I'm running the 3/10 nightly and have had mixed success with plugin  
automatic upgrade. I used it to upgrade Automatic SEO, worked  
flawlessly. However, using it to upgrade Extended Comment Options from  
1.1 to 2.0 ended with a failure in the last step and a deletion of my  
entire plugin folder (I keep backups of everything of course). I  
assume this is probably not the behavior that is expected :)
If there are any logs I can provide to help narrow down the cause,  
please let me know.
