Comment #30 on issue 1694 by nicolas.pourcelot: solve has many issues with  
fractions
http://code.google.com/p/sympy/issues/detail?id=1694

So, what should I do with singularities ?

I also noticed this recently :
>>> sympy.solve(exp(x),x)
[-oo]

If -oo if a solution of exp(x) == 0, so are -oo and +oo for 1/x==0...  
what's more,
oo+I*oo is a solution too, and so on.

So, before solving this issue, one must have a clear politic about what is a
solution, and what is not.
I can't make a proper patch without even knowing what I should obtain. :-)
