Summary	0012140: Convert to > Polygon crashes Scribus in determined condition
Description	Scribus 1.5.0 (18898) is not able to handle some changes to the nodes of Shapes.
Steps To Reproduce	0) Create a new document 1) Make sure windows > Outline is opened 2) Insert a Shape (default square) 3) Double click on the Shape so that "Nodes" windows appears 4) Select "Delete Nodes" (first line, third row) and delete one of the four nodes edge Now you won't be able to delete any other nodes. 5) Select the tool with the tooltip "Open a Polygon or Cuts a Bezier Curve" (first column, third row) and click on one of the three nodes 6) Delete one of the three remaining nodes (and close "Nodes" window) The Shape is now as not present, but a small red rectangle is shown as something is selected. From "Outline" you can see that the entry PolygonX is still present. You can increase its size from Canvas/Properties and double click on it (or from its entry in "Outline") but it will be always invisible. 7) Right-click on this Shape and Convert to > Polygon Scribus crashes due to Signal 6 So I believe that after Step 7 it would be more user-friendly to divide the Polygon in Multilines (as in Scribus 1.4.4 SVN (18899)).

Patch

FirasH 2014-03-11 19:24 reporter ~0031497	Re-tested a few times the Steps, but now I can't get to crash Scribus with Convert to > Symbol, but only with Convert to > Polygon. In Step 5 make sure to not move any of the nodes, simply click on the blue node (basically the preview of the nodes should look the same in Step 4 and 5).

FirasH 2014-07-29 10:49 reporter ~0033071	REDUCED STEPS (from 0012347): 0) Create a new document 1) Insert a Bezier Curve (B) with 3 or 4 nodes (reproducible also with more nodes after deleting the redundant nodes) 2) Double-click on the Bezier Curve so that "Nodes" window appears 3) Select "Delete Nodes" and delete one of the 3 or 4 nodes of the Bezier Curve 4) Go to: Item > Convert to > Polygon Scribus crashes due to Signal 6

Kunda 2014-07-29 13:20 updater ~0033073	Able to reproduce the issue using 0012140:0033071 and encountered bug 0012347 Crashed with Signal 6 10.8.5 1.5svn r19380

FirasH 2014-08-19 14:03 reporter ~0033285	Thanks jghali! The crash is not reproducible in 1.5.0.svn (19430) as it was a consequence of 0012347.

Kunda 2014-08-31 13:59 updater ~0033396 Last edited: 2014-08-31 14:00	Observations: 1. crash not present anymore 2. inability to remove a 2nd node as per step 6 3. strange phenomena (small red square) not presenting anymore 4. don't see the option to Convert to Polygon in step 7 (i see: convert to: bezier curve, image frame, text frame, symbol) Note: I was encountering some undo/redo bugs for example converting shape to: * * symbol * image frame * bezier curve and then undoing back to polygon. Bugs encountered: 0012299 0011365 (without the crash) perhaps more bugs need to be filed under undo/redo for image frame and bezier curve ?

FirasH 2014-08-31 18:26 reporter ~0033411	Thanks jghali! Fixed in 1.5.0.svn (19468).
