Comment 2 for bug 368545

Had exactly the same problem after upgrading from intrepid to jaunty. I made two changes (so I don't know which one fixed it). The first was to move it down in startup priority:

$ sudo mv /etc/rc2.d/S20stunnel4 /etc/rc2.d/S99stunnel4

This did not appear to help after a restart, so I decided to take a look at what was happening during startup, by removing the splash screen. This is done in /boot/grub/menu.lst, find the current kernel and remove the word "splash" from that line.

Restarted again, but the splash screen remained - so i did a full shutdown. Now the splash screen was gone, and stunnel started just like it should!
