Pattern Along Path LPE breaks namedview assertion

[Parcly Taxel]

The attached file causes trunk Inkscape (r14285) to crash on Trisquel 7.0 with the following message:

**
ERROR:../../src/sp-namedview.cpp:1053:SPNamedView* sp_document_namedview(SPDocument*, const gchar*): assertion failed: (nv != NULL)
Aborted

When I try with other paths with a Pattern Along Path LPE applied, the bug does not appear and the file loads normally.

On OS X 10.7.5:
- not reproduced with 0.91 r13725,
- reproduced with 0.91+devel r14285:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x0000000000000000
0x00000001007f0f87 in Geom::force_continuity ()

Based on tests with archived builds:
- not reproduced with rev 14224,
- reproduced with rev >= 14228;
likely a regression introduced with the latest 2geom update in r14226:
https://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/revision/14226

Based on the path geometry, and the backtrace (see attached), this is likely the same issue as already reported in
* Bug #1482806 “crash if Pattern-along-Path LPE applied to path with horizontal line segment (rev >= 14226)”

Proposing to link as duplicate to bug #1482806.

Crash not reproduced with Inkscape 0.91+devel r14293+patch from bug #1482806 - taking this as confirmation that the two reports share the same underling issue, and linking as duplicate to bug #1482806.

Feel free to add a comment here (bug #1484009) and revert the duplicate status if you disagree and think this was done in error.
