nxdialog clears clipboard

[uli42]

1. run an nx session (in my case a LXDE Desktop session) from Windows (maybe irrelevant)
2. mark something on the client side and copy to clipboard
3. paste somewhere in the LXDE session -> works
4. press ctrl-alt-e to open an nxdialog window
5. close the window
6. try to paste again -> does not work anymore

Note: if you are calling nxdialog --dialog ok in the session this also happens, maybe a bit delayed.
