Incorrect routing of multi-layer connectors on load

[Daniel Schmidt]

Using Inkscape 0.48.0 r9654, bug may be reproduced by opening a new document, creating a new layer ("Layer 2", above existing Layer 1), inserting two shapes in Layer 1 and one in Layer 2, and then using connectors to connect one shape in Layer 1 to the shape in Layer 2, then from the shape in Layer 2 to the other shape in Layer 1 - connections must be made to the exact center of each shape, i.e. such that the node in the center of the shape (I used circles for my test) changes from white to cyan. Everything looks fine, file may be saved as Inkscape SVG, but when reopened, both connectors have "lost" the shape in Layer 2 and are instead connected to the upper left-hand corner of the document.

<https://bugs.launchpad.net/inkscape/+bug/556467>

First tests show unpredictable behavior, apparently influenced by the stack-order of the layers.

[su_v (suv-lp)]

Connectors are incorrectly routed on load (and in the preview of the file dialogs) if one of the connected objects is on a different layer above (stack order).

Routing gets correctly recalculated e.g. if one of the connected objects is moved, or if an action (liking hiding its layer) is undone. Error persists on export to bitmap.

Example with connected objects on two layers (2 variants with different stack order, as well as the bitmap exported PNGs)

Not reproduced with Inkscape 0.46 and 0.47 on OS X 10.5.8

Reproduces here with 0.48.1 r9760. Would be nice to see this fixed since it is screwing up my files....

reproduced in 0.48.3.1
I was able to get the connectors to their correct place by pressing CTRL-Z when opening the file

Or by moving the connectors layer over the boxes layer

@Vit - your example attached here matches bug #795627 (which is about stack order: if connected objects are stacked above the connectors).
