Every time I log in, for some reason, I get a little box that pops up in the middle of my screen that says:

invalid option: -session

It just started yesterday and I'm not sure what is causing it. I'm running the 64bit version of Xubuntu 12.04 64-bit.

OK, I found the answer to this issue. I don't remember what it was off hand it's been so long ago but this question can be closed. – Jason Smith Aug 28 '13 at 1:21

I've got same problem on Xubuntu 12.10. Deleting the ~/.cache/sessions folder helps. I hope somebody will use that answer.
