I have been having same problem for a while. Inkscape crashes and gives the same error mentioned above. I was able to import .pdf and .cdr as well as .eps and .ai. However, now nothing can be imported.
At the moment I am using Inkscape 0.48+devel r11929 on Ubuntu Precise 64 bit.
I hope it is going to be solved soon.
