Comment 1 for bug 1630282

Based on tests with archived builds (on OS X 10.7.5):
- not reproduced with Inkscape 0.48.x (uses PaP LPE for triangle in/out)
- not reproduced with lp:inkscape r10895 (still uses PaP LPE)
- not reproduced with lp:inkscape r10896 (switched to Powerstroke LPE)
- not reproduced with lp:inkscape <= rev 13477
- reproduced with lp:inkscape rev >= rev 13481
- reproduced with Inkscape 0.91 r13725, lp:inkscape/0.92.x r15094.

The crash was possibly exposed with changes between 13477 and 13481:
