'Assertion failed' in diagrams (connector tool)

[Remi B]

I use the version "inkscapeR9412-1005140043.7z" under Vista. If I play a few minutes with diagrams (only rectangles and connectors) assertion failed happens, then it occurred when clicking on the "Make selected objects known connectors".

Assertion failed:
   Program:...
   File: src/libavoid/shape.cpp
   Line:81
   Expression : !_router->shapeInQueuedActionList(this)

Best regards

reproduced with Inkscape 0.47+devel r9479 on OS X 10.5.8

console message:
Assertion failed: (!_router->shapeInQueuedActionList(this)), function ~ShapeRef, file libavoid/shape.cpp, line 81.

Confirmed in rev 9441 Vista64

In addition, the 2 leftmost buttons can not be selected (hence, should be either disabled or selectable)
From the topright to the rectangle in the middle (see fig), it is not possible to disallow overlap.

The error window pops up when for example
1) creating the connector between the topright and the rectangle in the middle (orthogonal connector must be selected).
2) Then selecting the rectangle in between the two.
3) selecting the leftmost button in the button bar
4) selecting the second button in the button bar

AFAIU these are not 'state' buttons, they execute the command for the selected objects (like the reset button on the ellipse and star toolbar)

This should be filed separately IMHO: the rerouting around avoided objects works far better in orthogonal mode, unfortunately a regression compared to 0.47.

The same crash happens when trying to reproduce bug #546752 “Crash when ungrouping a connector that avoids a shape” with Inkscape 0.47+devel (bug #546752 was filed against 0.47, see my comment #4 there):

These actions crash Inkscape 0.47+devel:
- removing the attribute 'inkscape:connector-avoid' on an object using the second toolbar button ("Make connectors ignore selected objects")
- grouping objects with the attribute 'inkscape:connector-avoid'
- deleting an object with the attribute 'inkscape:connector-avoid'

updated list:

2) grouping objects with the attribute 'inkscape:connector-avoid'
3) deleting an object with the attribute 'inkscape:connector-avoid'
4) converting a shape with the attribute 'inkscape:connector-avoid' to path

Fixed in r9709 of the trunk.

Setting milestone to 0.48: the fix (r9709 in trunk) had been backported to 0.48 in r9654 (last revision before the release)
