I doubt that she introduced any, because patch for nginx-0.8.8 applies 
cleanly (without any modifications) against latest nginx.

Anyway, this "bug" you were seeing appeared when original patch was applied 
against nginx-0.8.11 or newer (long story short: r->cache->body_start was 
never set and nginx tried to read 0 bytes). This is fixed now.

It was created as a patch, because we (Johan Bergstr?m from yo.se, who 
funded this patch and me) hoped that it would be imported to nginx's base 
someday.

Patch against nginx-0.8.26 is available at:

In the future, please report when you find bugs ;)
