6423	Sage not always understanding i=sqrt(-1)  - Maxima bug probably	drkirkby	AlexGhitza	"Vladimir Bondarenko (a developer of software to test computer algebra systems - see [http://www.cas-testing.org/] ), had been playing with [http://demo.sagenb.org/] and noted the following:
{{{
exp(-x^i).integral(x,0,1)  returns

Traceback (click to the left for traceback)
...
Is %i an integer?

Ouch! Any Sage comments?
}}}

When I reported his on sage-devel, William Stein said:

''A large amount of the symbolic functionality that uses Maxima has
issues like this, but unfortunately there is basically nothing we can do about it, except continue with projects to rewrite the parts of Sage that call Maxima so that they don't call Maxima.  So this class of bugs should be very good motivation to continue to work on
implementing symbolic integration ourselves (and/or further improving sympy!).''

He then went on to say he wanted it reported as a TRAC bug but was busy, so I have done it on his behalf. 

I don't feel able to comment much more on this, and personally don't intend trying to fix it (outside my knowledge), so I've just reported it. 

Can someone else add appropriate priority, milestones, keywords etc, as this is completely outside my ''comfort zone''.
