sample ods file with "many" sheets

This is a sample ODS file that kills my Calc performance. Just to open the file
takes 20 seconds, to switch to a different sheet takes 15 seconds. During that
time my GNOME desktop is frozen and I can't do anything else. I believe this is
caused by sheet tabs redrawing at the bottom of the document.

I've tested this on Fedora 20 with mesa 9.2.5, kernel 3.12 with dpm,
xorg-x11-drv-ati 7.2 and xorg-x11-glamor 0.5.1. I tried to install Fedora 21
today to have the latest software to test, unfortunately the radeonsi driver is
unusably slow in there (no errors in the log, no idea why), so I can't speak
for that.

I'll also try to find a different document that I can share where scrolling is
a problem, not just the number of sheets.
