Persistent Login module conflicts with fbconnect module. The result of having both modules enabled is that logging out becomes impossible - the user is continually presented with a 'welcome back' dialogue.
Changing the weight of Persistent Login to -1 appears to fix the issue.
Perhaps someone else could test and confirm this is a 'safe' solution.

gappleSince 5.x-1.x has not been supported for some time, I'm closing this issue.
Please re-open with steps to reproduce if it still occurs in 7.x-1.x
