I am runnung Ubuntu 14.10 64-bit and Inkscape 0.48.5 r10040 (from official repo).
To me, it seems to happen earlier the heavier the file is. After inputting some text characters (about 20 in a 38MB file), suddenly it slows down and freezes. No significant CPU or RAM usage.
The only output from the terminal is "inkscape: Fatal IO error 11 (Resource temporarily unavailable) on X server :0." when I close it.
Same thing for me.
