Comment (by phk):

 I belive this problem is already solved in trunk, as part of the change to
 eliminate storing the unhashed hash input string.

 For 2.x I think a better way to solve it, is to make the first codeblock
 in cache_center.c:cnt_lookup() conditional on sp->objhead == NULL.

 In fact, I don't think the "if (sp->obj == NULL)" makes any sense now that
 I look at it, it was probably a mistake for that to not have been changed
 to "if (sp->objhead == NULL)" at some point in the past.

 Can I get you to test that change, and see if it solves the problem ?
