I get the same problem as well.

Out of these, only #10868, #10923, # 11483, or # 11591 seem to even be
possible suspects.
#10868, #10923, and #11591 are pure documentation patches.
#11483 finally adds abs_integrate to our default, but that doesn't seem to
change Dima's result in vanilla Maxima.
(%i2) load(abs_integrate);
(%o2) /Users/.../sage-5.0/local/share/maxima/5.26.0/s\
hare/contrib/integration/abs_integrate.mac
(%i4) keepfloat:true;
(%o4) true
(%i7) integrate(ln(1+4/5*sin(x)), x, -3.1415, 3.1415);
3.1415
/
[ 4 sin(x)
(%o7) I ln(-------- + 1) dx
] 5
/
- 3.1415
And we have
sage: maxima_calculus(" integrate(ln(1+4/5*sin(x)), x, -3.1415, 3.1415);")
'integrate(ln(4*sin(x)/5+1),x,-3.1415,3.1415)
so something must indeed be wrong in how we're sending this to Maxima.
I've opened http://trac.sagemath.org/sage_trac/ticket/13097 for this.
