shape draw with "hand free line" disappear when combined

[olivier etienne]

1. select the handfreeLine tool
2. set the shape to ellipse
3. draw two lines
4. select the two line previously created
5 select Path -> Combine
6 Both shape disappear

Was working fine in previous version of inkscape 0.48.5

In Inkscape 0.91, using the shapes 'Triangle In' or 'Triangle Out' with the pen or pencil tool applies the new Powerstroke patheffect [1], which does not support compound paths. OTOH the new patheffect offers more options for variable stroke width along the path than the previous implementation via 'Pattern along path' path effect.

The old type to produce paths with (less but still) variable stroke widths can still be manually applied via "Path > Path Effects" dialog, in case the usage of a patheffect for a variable stroke width applied to a compound path is required.

Changed behavior in 0.91 with 'Ellipse' as shape reproduced with Inkscape 0.91 r13725 on OS X 10.7.5: the shape 'Ellipse' still uses the 'Pattern along path' path effect, and works as described in Inkscape 0.48.5. The changed behavior when combining paths with this path effect applied is unexpected.

[su_v (suv-lp)]

Based on tests with archived builds on OS X 10.7.5:
- not reproduced with 0.91+devel rev <= 13477,
- reproduced with 0.91+devel rev >= 13481;
this changed behavior is possibly a side-effect of rev 13479 (to be verified):

The expected rendering of the path effect of the compound path can be restored e.g. by toggling the visibility of the applied patheffect in the path effects editor dialog (off and on again).

[su_v (suv-lp)]

The regression can also be reproduced with latest trunk (r13950) - after combining two paths created with shape 'Ellipse', the resulting compund path disappears - and the same workaround to restore the expected output of the path effect also applies - toggling the patheffect 'Pattern Along Path' off and on again in the 'Path Effects' dialog.

[Liam P. White (liampwhite)]

Can confirm that regression was introduced with the changes in r13479 — all this nastiness (and bug #1299948) really needs a closer look to determine what really needs to be going on here; this was a hack workaround.

Fix committed to lp:inkscape r13954 - would be nice to see this backported to 0.91.x.

thx!
