Pen tool: Crash when using new Shift+Enter shortcut (0.92pre2)

[Hachmann]

I've been trying out this new shortcut for the Pen/Bézier tool, to auto-close a path (see https://bugs.launchpad.net/inkscape/+bug/1324252) with 0.92pre2.

It crashes almost every time (with emergency save), when in Spiro or BSpline mode.
Error message is 'Speicherzugriffsfehler' - segmentation fault. Works fine in the other modes.

Reproduced with Inkscape 0.92pre2, lp:inkscape/0.92.x r15145 (on OS X 10.7.5).

Couldent reproduce on debian stretch and lp:inkscape/0.92.x r15145, througth X2go.Several trys.

A step by step os more advanded backtrace, with bug line number if posibol to try to fix on the dark.

I try to fix in the dark: Attemp 1

[Jabiertxof (jabiertxof)]

Attemp 2. One of this maybe fix the problem

Sorry, I can only provide the step-by-step description / backtrace, but can't test the fix:

1. open new document
2. switch to pen tool, select Spiro mode (or BSpline)
3. Click with pen tool on canvas at least 5 times (doesn't crash when only 3 or 4 times)
4. Hit Shift+Enter -> Crash.

The backtrace I get is attached, but will probably not give any further insights.

Still coulden't reproduce, now without x2go -remote control-
Anyone could compile to try the patches?
Cheers, Jabier.

[Jabiertxof (jabiertxof)]

Fixed in trunk r.15210 and in 0.92.x in r.15150.

Yay, thank you, Jabier! :D (...*edits the release notes*)
