My fault.  I removed a call to RegisterClipboardFormatW without
realizing that this will break the clipboard after execve.  Sorry about
that.  I just applied a patch which fixes this again.

Please test the today's snapshot from,
which should show up in the next couple of hours.

Thanks for report and thanks in advance for testing,
