Converting groups to sublayers triggers crash in trunk

[su_v]

Follow-up report to Bug #1066543 “Performance regression with layers in trunk”.

Current trunk >= 11709 crashes when applying a custom extension [1] to convert a selection of groups into sub-layers. The custom extension that triggers the crash was used in an effort to work around the huge delays (40-60 sec) when adding a new (sub-)layer via GUI in certain files (bug #1066543).

Steps to reproduce:
1) mv ~/.config/inkscape{,-bkp}
2) install attached extension
2) launch inkscape (without file)
3) open attached SVG file via 'File > Open'
4) select all (9) groups in current layer ('Ctrl+A')
5) apply 'Extensions > Layers > Selected Groups to Sublayers'

-> crash

Notes:
- not reproduced with Inkscape <= 11708 and current stable 0.48.x.
- not reproduced if the file is opened in a new second document window (e.g. after having dirtied the initial empty new document before opening the file).

Tested on Mac OS X 10.5.8 (32bit), OS X 10.7.4 (64bit) and Ubuntu 12.10 (64bit, VM).

Backtrace with Inkscape 0.48+devel r11882, OS X 10.7.4, GTK+/X11 2.24.13, glib 2.32.4

confirmed on Windows XP, Inkscape rev 11882.
It appears that the crash occurs whenever more than one group is selected.

[Alvin Penner (apenner)]

as mentioned in comment 1, it seems to depend on how the file was loaded. On Windows if I load Inkscape first and then use File->Open to load the file, then I get a crash. On the other hand, if I use the gui to do a right mouse click on the svg file, and select Open with Inkscape, then I get no crash.

Changes in bug #166691 reverted ( r11883 ) - should solve this issue.
