Correction to my previous reply: in 8.0.1 (Mac), your second integral indeed crashes the kernel reproducibly. In v9, it works fine:
Integrate[x/Sqrt[x^2 + y^2], {y, 1/2, 3/2}, {x, 1, 1/2  y}]
1/32 (2 Sqrt[5]  2 Sqrt[13]  16 ArcSinh[1/2]  16 ArcSinh[3/2] + Sqrt[2] ArcSinh[3] + Sqrt[2] ArcSinh[5])
Integrate[x/Sqrt[x^2 + y^2], {y, 0.5, 1.5}, {x, 1.0, 0.5  y}]
0.741019
