A lot of tests in fast/workers/storage/ seem to have the following error

2010-10-17 21:17:04.268 DumpRenderTree[42509:bd9b] ***
_NSAutoreleaseNoPool(): Object 0x218a8890 of class NSCFString autoreleased
with no pool in place - just leaking

Stack: (0x955d2f4f 0x954df432 0x252508d 0x5c4d18 0x1c50230 0x1c4d649
0x263ea0d 0x22edba0 0x1e3f3bc3 0x355eeb)

See http://build.webkit.org/results/Leopard%20Intel%20Release%20(Tests)/r69939%20(22816)/results.html
for example.

According to Catfish_Man:

It means something is using Cocoa strings without proper setup, essentially.
> in a normal Cocoa app, NSApplication would set up a root autorelease pool
> that those would fall into. In something like DRT it would need to do so
> itself before using them.

Is this a known problem?  If not, can someone work on this issue?
