Bug Description

Greetings and salutations! This might not be a bug, this might be user error.

All of the paths in the enclosed SVG cause the following lib2geom error:
terminate called after throwing an instance of 'Geom::Exception'
  what(): lib2geom exception: assertion failed: B.isFinite() (2geom/sbasis-to-bezier.cpp:348)

Are they malformed in some way?

Let me know if there is further information I can provide.

I'm running Inkscape 0.48+devel r11487 (Jun 12 2012) on Kubuntu 12.04

Thanks.

Inkscape crashes when trying to open the file (I did not extract individual paths to test each of them separately).

Crash not reproduced on Windows XP (32-bit) with 0.91, 0.92.x rev. 15025 and trunk rev. 15028. But as I never managed to reproduce the bug on Windows (see comment #5), it's not very relevant.

Note that with 0.92.x and trunk, the fushcia path doesn't render and the console shows the following message (repeated 6 times):
** (inkscape.exe:3336): WARNING **: Exception during LPE Contour dynamique execution.
 lib2geom exception: rx2 < 0, while computing 'rx' coefficient (src/2geom/ellipse.cpp:81)

The trunk version has the same issues I had with Windows XP (error messages and missing path). See previous comment.

milestone: none → 0.91
