Summary	0012249: Deleting Bezier Curve nodes crashes/freezes Scribus in determined condition
Description	Deleting Bezier Curve nodes may crash or freeze Scribus following the described Steps.
Steps To Reproduce	0) Create a new document 1) Insert a Bezier Curve with 3 nodes 2) Double-click on the Bezier Curve so that "Nodes" pops up 3) Select the tool to delete nodes (first line, third row) If you want Scribus to crash follow these steps: 4) Delete the node in the middle of the Bezier Curve (not first or last) Now the delete nodes tool is not selected 5) Select the first node of the Bezier Curve 6) Select the tool to delete nodes (first line, third row) (this can be reproduced following a different way of deleting nodes, but this worked always for me) [Scribus 1.5.0: deleting the middle node (step 4) deletes completely the Bezier Curve leaving only a small rectangle (selection) and the entry "PolylineX" in Outline window.] Scribus crashes due to Signal 11 If you want Scribus to freeze follow these steps (do not work always): 4) Delete the last node of the Bezier Curve 5) Try to delete one of the remaining 2 nodes [Scribus 1.5.0: deleting the last node (step 4) deletes completely the Bezier Curve leaving only a small rectangle (selection) and the entry "PolylineX" in Outline window.] If Scribus doesn't freeze its very likely that the Bezier Curve is invisible on Canvas and only a very small red rectangle (selection) is visible. In Outline window the entry "PolylineX" is still present.

Kunda 2014-06-17 04:56 updater ~0032208	Partially reproduced on r19244 (OSX 10.8.5 Homebrew build w/ Homebrew packaged Qt5.3) Not reproducible each time (for both scenarios) on 1.5svn (it's an elusive bug)

FirasH 2014-07-25 23:36 reporter ~0033008	The crash is fixed with 1.4.5.svn (19369). The freeze is still reproducible.

FirasH 2014-09-01 19:33 reporter ~0033438	Seems fixed as I cannot reproduce the freeze with 1.4.5.svn (19469).

Kunda 2014-09-01 19:49 updater ~0033439	Cannot reproduce either on 1.5svn r19469 (OSX 10.8.5)
