Comment 8 for bug 1125631

In addition,

As could be guessed from clipboard containing vector data, the problem is fixed if and only if receiving inkscape is closed and reopened. Clipboard data remained unchanged in between. Also text element copy works after restart.

Cannot reproduce, but as above commenters, I have had several instances open for long time. The receiving inkscape process and file was opened 12h earlier, but only worked with it for ~2hours.
