bug? triggered by deleting cookie?

I have been trying without success to log into the Control Panel for
one of my web domains using Netsurf #1276 on Iyonix 5.18.

Advice from Neil Spellings (who hosts the domain) is that it's a
"session" matter and to delete the cookie. I did that, and soon
Netsurf crashed. Relaunched Netsurf, noted the long cookie list is
now down to just two items, deleted one, repeated the process, and
Netsurf promptly crashed again.

Log is here (since I have no luck in using Netsurf to report a bugs
via Sourceforge): www.archivemag.co.uk/JN/TEMP/NSLog130724.txt (only
35K after fresh relaunch).

Trying to relaunch Netsurf fails with an error (can't quote it because
it failed to record itself in Syslog) but a second attempt succeeds.
Peculiar.

Why, by the way, does deleting the cookie require two attempts? This
is from menu over the Netsurf window, "Utilities > Cookies > Show
cookies...", select the required item, do menu "Selection > Delete".
Check the list of cookies again, the item is either back or still
there, so repeat the whole menu business.

Still haven't got to my Control Panel. Besides deleting the cookie,
is there something else I need to do to resolve the "session"
difficulty?
