Howdy, 

One of my users is getting a crash while trying to delete waters.  He has
tried an older 0.6 version on OS X Intel 10.4 and the latest 0.6.2-pre-1 on
10.6 with the same results.

Here are the last few lines from the terminal before the crash:

(set-delete-residue-mode)
Click on an atom in the residue that you wish to delete
(set-delete-residue-water-mode)
(4)  O  /1/chainid="W"/4/HOH,  occ: 1 with B-factor: 30 element:  O at

debug:: delete_atom: we have a matching residue 4 ::

 line 5:  1905 Bus error
/programs/i386-mac/coot/0.6/bin/coot-real "$@"

He also reports "the waters were generated in COOT using the "find waters"
function under "Other Modeling Tools."  I do not have this problem when
deleting waters that were generated in Phenix, so it seems to be something
peculiar about these waters.  I have tried saving the coordinate file, then
reading back in the file, but the program still crashes.  I cannot see
anything obviously wrong with the PDB file."

And he provided an excerpt:

CRYST1   62.812  107.334   86.998  90.00 100.61  90.00 P 1 21 1

Any ideas?  We can provide more info if needed.

Thanks.
