Undo Stroke to Path destroys clones, crash

[Stratadrake]

Encountered in Inkscape 0.48.0 (will attempt in 0.48.1 when available):

1 - Create any convenient object on canvas and then clone it. Move the clone somewhere convenient.

2 - Select the original object and convert its stroke to a path (Object > Stroke to Path).

3 - Select Edit menu > Undo. At this point, all clones of the object have disappeared from view.

4 - Select the master object and clone it again. Nothing happens; statusbar reports "Orphaned Clone in (Layer). Use Shift+D to lookup original" .

5 - Edit menu > Clone > Find Original (Shift+D). Statusbar reports "Cannot find the object to select (orphaned clone, etc.)".

6 - Edit menu > Clone > Unlink Clone. Crash.

So far this only occurs with "Stroke to Path". "Object to Path" does not reproduce this behavior or the crash.

> 6 - Edit menu > Clone > Unlink Clone. Crash.

The crash has been fixed in trunk and the branch for 0.48.1, see
Bug #675309 “crash when unlinking an orphaned clone”

Steps 1-5 reproduced with Inkscape 0.48+devel r10000 on OS X 10.5.8:
(step 6 and resulting crash when unlinking orphaned clones has been fixed).

The clones are not actually destroyed - if you save the document after step 4 and reopen it, all clones are present and displayed as expected.

Still repro.
