Maybe you can try with another version of Blender ?
try some of the old official versions
And if you want to work on the latest blender version, what you can do is just use the 2.5.2 to convert the .dae to a .blend (for instance), and then re-use the latest Blender version.
Oh, and as Auria said, it would be nice to report the bug to Blender developers
