Ok, I've been running into this problem for quite a while...
I have some files, I based on svgs exported with corel. So now everytime
I import them into a new document they are huge, huge, huge. I don't
really consider it a bug, since once I import them, scale them down and
save it'll work fine.. also graphics directly created with inkscape work
fine. If I just open them, they show the right size as well.
It's just kinda annoying, you know.
I've a file attached so you can tell, what I'm talking about.
