WebPositive triggering : vm_page_fault: vm_soft_fault returned error ...

hrev35761-2hybrid. WebPositive is able to trigger vm_soft_faults easily. revisions 265, 272, 283 of Web+ were tested and all behaved in the same manner. When navigating to most sites, www.haiku-os.org, www.engadget.com, Web+ will crash, with syslog/serial debugging capturing either of two error messages

It was mentioned over IRC that this appears to be a Web+ bug most likely. Sorry for the noise.
