Evolution will not empty trash folder
 

I am running FC1 with Evolution 1.4.5 as my e-mail client. No matter how I try I cannot empty my trash folder. It's really no big deal except things are starting to pile up in there and take up disk space.
I do have it set to empty the trash on exit but the same messages are still in the trash folder when I run it again. I have selected the messages in the trash and hit the delete button on the toolbar to try to get rid of them and this doesn't work either.
I have uninstalled the Evolution rpm and the .evolution folder in my home folder to no avail.
How can I get rid of these messages piling up in the trash folder?
