Inkscape trunk actually handles this file rather well on Linux on my box. It opened in less than 30 seconds, changing zoom levels takes ~10 seconds at most in my testing.
Note: I did test against the 0.48.x tree and the performance was horrible as expected. I opened 0.48.x and chose to open that file. Window dimmed as unresponsive. While that process was running I opened a copy of current trunk, chose to open that file. It took as little time as I mentioned above, zoomed around, etc... by the time I was done and closed it, 0.48.x still hadn't become responsive yet.

Closing as Fix Committed for 0.49.
