Perhaps the tile-setting was other than 1,1,1 in your image /
bumpmap_generator node?

Yeah I'm sure clamp was in there, but if I apply an xy to an object,
without scaling it, the bump should cover the whole object, even with
clamp checked. In this particular case, it didn't, which means either
there was a problem with my object/scene, or there's a bug in the
software. Having deleted all projections etc. it then worked, so
that's fine.
At the moment I have about 4 or 5 little niggly things, which at the
moment I can't pin down as bugs or just changes in workflow, or whatever.

Well, clamping cuts everything outside the range of the texture, so
this behavious is expected, but I'm not sure about the reason for
this feature, probably some sort of optimization in case you don't
need unclamped values. I'm pretty sure it was there in earlier
versions as well. When you map something as absolute UV's this wont
occur, but if you tile your textures or go outside the range [0..1]
in your UV coordinates this will happen. Guess it's one of those
things you gotta keep in mind while working with shaders.

Thanks Arvid, that worked, though it doesn't explain why the xy
projection covering the whole object, just rendered in the corner. I
ended up deleting all texture-supports and projections and applying
new ones. I had another similar object with no visible bumpmap, and
when I un-checked clamp, hay-presto there it was.
I've got to say, we're experiencing lots of little 'issues' with 5,
that we didn't have with 4.2
