[Well, please  bear in mind you're running unstable development code if 
you're running bzr head rather than a release AFAIU]

If you just want shift-arrow selection, note that that has worked in 
emacs anyway for a while, without pc-selection-mode turned on as such.
But since your bug was for the delete-selection part, well, I guess 
that's less than satisfactory.

The problem is likely in delete-selection-mode (which pc-selection-mode 
uses underneath) or some of the code it calls in simple.el:

I was totally expecting this to be related to certain recent changes in 
default selection handling, but breakage happened in my short test even 
with them turned off on X11 emacs on debian.  It may/must still be 
related to recent rearrangements, of course, just perhaps not in the 
area I thought.

I for one won't get to look properly at this until the weekend, though 
I'm not the only person about.
