Comment 0 for bug 1063523

A FS Dash performs quite poorly, at here with nouveau drivers.
It will quickly go from very slow to major video degradation, both in the Dash & unity panel.
After a couple of openings the Dash Icon may stop responing to r. clicks & .xsession-errors reports
"nouveau: kernel rejected pushbuf: Cannot allocate memory
nouveau: ch4: krec 0 pushes 1 bufs 151 relocs 0
nouveau: ch4: buf 00000000 00000005 00000006 00000006 00000000"
ect.
Attached is a truncated .xsession-errors, removed about 100,000 lines, each subsequent attempted opening of the Dash will write about 100,000 lines or more additional lines until the system eventually locks
