Forget version, Inkscape 0.47 on Archlinux x86_64

[Alvin Penner (apenner)]

Confirmed on Windows XP, Inkscape 0.47 r22583 (Nov 21 2009), exit message is:

terminate called after throwing an instance of 'Geom::ContinuityError'
  what(): lib2geom exception: Non-contiguous path (src/2geom/path.cpp:88)

- however, no crash on bzr rev 9073

[su_v (suv-lp)]

reproduced with Inkscape 0.47 r22583 on OS X 10.5.8
not reproduced with Inkscape 0.47+devel r9089

looks like some recent changes have fixed this, but I have no idea what causes the crash and what fixed it.

[su_v (suv-lp)]

console message is the same, crash log including backtrace on OS X 10.5.8 with Inkscape 0.47 r22583 attached.

[Johan Engelen (johanengelen)]

i vaguely remember fixing reading of rare svg strings, and some other path continuity problems. usually they stem from adding a path node with infinite coordinates.

Can we confirm that it is fixed, and mark the bug as such?

not reproduced with Inkscape 0.47+devel r9104 on OS X 10.5.8
