Hello,
as a SymPy newbie, do I do something wrong here?
In [1]: solve([x**2 * y**2 <= x**2 * y, x**2 * y**2 > x**2 * y])
ERROR: An unexpected error occurred while tokenizing input
The following traceback may be corrupted or invalid
The error message is: ('EOF in multi-line string', (1, 38))

I am using the current Git head (commit b7c9ba).
