I am running Gnumeric version 1.10.13, which I obtained through the Ubuntu software center. I am running xubuntu 11.04, and neither ps nor dpkg -l reports anything with "clip" or "Clip" in the name, so I don't think I am running a clipboard manager (which seems to be the resolution of some similar bugs I found searching in bugzilla).

Here's a description of what I am seeing and how to reproduce:

a) Put some data in one or more cells. It doesn't matter if I use one cell or multiple.
b) Use the mouse to highlight/select the cell(s).
c) Use the cut command. It doesn't matter if I use control-x, or Main Menu / Edit / Cut, or right-click menu / Cut -- the behavior is the same.
d) Click somewhere else on the sheet and attempt to paste.

What I expect to happen:
The cut data is pasted in the new location.

What does happen:
Nothing is pasted.

Note that copy/paste does work fine, it's just that cut/paste does not. I also tried cut / paste to another application, and what is pasted is whatever was previously in the clipboard. Copy/paste to another app works fine. Cut or copy from another app into Gnumeric works fine too.
