[Scribus] imported from Inkscape... lines changing ?

[stu seven]

   I noticed an unwanted effect yesterday after
importing an Inkscape SVG into Scribus...
  ...I got the picture OK, but now it has some ROUNDED corners where I
had SQUARE corners ?!?
     This could be an interesting effect maybe...
but not what was intended... is this, possibly,
a Scribus bug... or should I be bugging the
Inkscape forum ?   :)
Anybody seen similar ?
Thanks
