iPhone Dev Team has updated their redsn0w tool to version 0.9.10b4 that addresses the critical iBooks crashing bug. The latest Redsn0w jailbreak also fixes sporadic issues with launchctl.

It is therefore highly recommended to install redsn0w 0.9.10b4 over redsn0w 0.9.10b3 or update Corona 5.0.1 untether to 1.0-4.

The root cause of iBooks issue fix was first identified by @xvolks who earlier patched the kernel sandbox by including @comex sandbox patches into the Corona GIT.

Last week @xvolks released a standalone tweak xBooks hat completely fixed the iBooks error on iPhone 4, 3GS, iPad and iPod touch. But then later he handed over the hack to Musclenerd and Chronic Dev team to package into Corona and Redsn0w 0.9.10b4
