[ShellShock]

Hello Calibre gurus! Can anyone help with the following error, or am I stuffed? My input mobi is 20 MB, calibre-parallel.exe memory usage goes up to about 700MB before the error happens. I am using Windows 7 64 bit with 8GB RAM, approx 4 GB RAM free when the error happens. Thanks muchly. PS the Mobiunpack plug-in also fails with a memory error.
