It seems that I have an egg install of version 1.1.6., and here's a
traceback:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

It looks like something is now passing a dpi keyword argument to
print_jpg, but something inside PIL is expecting its value to be a
sequence. I'll commit a fix.

Virtualization is moving to the mainstream and overtaking non-virtualized
environment for deploying applications. Does it make network security
easier or more difficult to achieve? Read this whitepaper to separate the
two and get a better understanding.
