gedit event after upgrade

[widda]

Strange line of text appeared on open gedit page on first use after upgrade from 10.04 t0 10.10. I was reading something and copypasting the odd bit onto a gedit note: left the room, returned to find blank page except for "nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn". Then I saw that it was just the tail-end of a longer line which had stretched the page width to max, and by deleting backwards I arrived beneath my intact notes. The line was
"I[my bolding]nnnnnnnnnn...nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnby v9898".

I googled v9898. And there's a v9898. com. It provides something for Windows systems.

Anyone?

Of course it may be nothing to do with upgrade. I may move it elsewhere soon.
