We get a noun form because Maxima can't find a limit of an incomplete gamma function.  Repair this limit limitation, and I think this definite integral will give a correct value:
~~~
(%i3) integrate(exp(-t) * log(t), t, 0, 1);

(%o3) 'integrate(%e^-t*log(t),t,0,1)
~~~
This is a test in `rtest_log` (problem 120 , line 433)
