Inkscape crash when ungrouping an imported SVG with connectors

[Pablo Aguilar]

I'm attaching a file that makes Inkscape crash. It crashes Inkscape 0.48 just by opening it. Inkscape 0.48.1 doesn't crash when opening it, but trying to ungroup the drawing (everything is in one group), crashes as well.

Please add information about your OS/platform.

The bottom part of the drawing is one group, I can ungroup that with no crash. I can also select all and ungroup everything with no crash.

This is with both 0.48.2 (to be released soon), and Inkscape trunk.

This looks to be a duplicate of bug 771738.

@Scislac - I disagree ;)

Crash reproduced on load with Inkscape 0.48.0 on Mac OS X 10.5.8 (i386)
Crash not reproduced on ungroup with Inkscape 0.48.1: "everything is in one group" is not true, did you attach the correct file? No crash when ungrouping the large group in the bottom half of the drawing.

Based on the console message and backtrace of the crash in Inkscape 0.48.0, this is a duplicate of
Bug #511577 “segfault in sp_shape_update_marker_view()”
<https://bugs.launchpad.net/inkscape/+bug/511577>

Console message:

I'm using Windows 7 64-bit. Inkscape 0.48.0 is installed and 0.48.1 is the portable version. Apparently, Inkscape saved the ungrouped file upon crashing, and I no longer have the original one.

[ScislaC (scislac)]

Pablo: Does the modified one still crash on you?

~suv: Great... so now I need to install 0.48.1 too... :(

[Pablo Aguilar (pablo-aguilar-u)]

Found another way to make Inkscape crash, though:
1) Open a new blank drawing
2) Drag the file (from Windows explorer) into the blank document (now its all in one group)
3) Ungroup => Crash. Error message here: http://tinypic.com/r/23urfo6/7

Unlinking as duplicate from bug #771738: there are no orthogonal connectors (connector-type="orthogonal") in the attached file:
