The svg:path element lacks a "/> at the end.  When that is added, it
loads in 0.90.  Apart from that, I think this is related to 89640.

Sorry, the path line didn't get pasted fully the first time arround...

The following shape (without the path element) produces the same error
with dia 0.90(I don't know XML as you see):

I attach a tar of my .dia directory and a test file...

Comment 4 raiman 2003-01-31 23:07:12 UTC

It may indeed be related to 89640 as I don't have gsfonts installed,
but dia crushes before it gets to complain about the fonts as it
usually does.
