moving an object to <defs> can segfault the app

[Alexander Sedov]

Steps to reproduce:
1. Make a graphical object.
2. Make a <use> element either via Clone (Alt-D) or manually.
3. Attempt to move an object over to <svg:defs> section.
4. Get a segmentation fault: ERROR:xml/simple-node.cpp:414:virtual void Inkscape::XML::SimpleNode::addChild(Inkscape::XML::Node*, Inkscape::XML::Node*): assertion failed: (!ref || ref->_parent == this)

Can't reproduce. Which inkscape version/OS are you using ?

[Alexander Sedov (alex0player)]

Debian Stretch repository version (0.91). Once I get home, will try to
narrow it down more.

Correction: after making a clone, apply any transformation to the clone (for example, move it), and then move the original to <defs>.

Updated bug description, thank you!

[jazzynico (jazzynico)]

Not reproduced on Windows XP, Inkscape 0.48.5, 0.91 and trunk rev. 14696.

[Alexander Sedov (alex0player)]

Unable to reproduce on Windows 8 as well. Still reliably reproducing on Debian stretch, v 0.91 r13725.

[Mc (mc...)]

Reproduced on Debian stretch, v 0.91-7+b1 , not reproduced on trunk 14696

[jazzynico (jazzynico)]

Not reproduced on Xubuntu 15.10, Inskcape 0.91-5ubuntu2 and trunk rev. 14696.

Libxml2 changed in stretch (2.9.3) and that new version might have revealed a bug in Inkscape.

[Mc (mc...)]

Can anyone reproduce this with trunk ?

[jazzynico (jazzynico)]

Not reproduced on Xubuntu 16.04, Inkscape 0.91-7ubuntu2 and trunk rev. 14995 (libxml2-2.9.3).
@Mc-, it's weird I can't reproduce with 0.91 since we share (almost) the same Inkscape and libxml2 version (yes, I did move the clone before editing the object in the XML editor).

[jazzynico (jazzynico)]

@Alexander, could you please test again with the latest Inkscape stable in Stretch (you should now have a 0.91-9 version)?
Thanks.
