Can you reproduce it? Can you give a testcase?

Today my production system threw a NullPointerException:
(See stack trace below)
This is with wicket 1.2 final (for line-number references).
The line the NPE occured is:
"session.removeAttribute(attributeForId(entry.getNumericId()));"
i don't have any customized stuff here, nor do i have more than one
pagemap, so i'm tempted to declare this as a reace condition-triggered
bug. (because it just occured today, after 4 weeks without problems, but
today the app was quite busy, lots of concurrent requests...)
Any ideas?
