Assuming - based on the reporter's other reports, though no information about the OS was provided here - that this is related to (or a duplicate of) the known issue with the XQuartz pasteboard (not really an Inkscape bug) as tracked for Inkscape in bug #307005.
Unfortunately this report lacks any further information as well - is this about an attempt to copy and paste between an X11 application and native OS X apps (won't work because this transfer, handled completely outside of inkscape, is partially broken and limited to rasterized data AFAIK), or between X11 applications?
