[Evolution] Safe to delete .debris folder? Y/N?

[Andy Proctor <andy gpshelp co uk>]

Hi All, 

I have been doing some routine housekeeping and notice that the Evolution subfolder called .debris contains lots (thousands) of files (totals over 300MB). Am I safe to delete this folder and what is its purpose? (It doesnt seem to be the trash as I empty that on close. 

Thanks

Andy

PS I know I can move it somewhere else, but really interested to know what it is first.
