Comment 5 for bug 168173

Originator: NO

I can reproduce this /sometimes/ using svn head (on linux with gtk 2.10.6
/ gtkmm 2.12.2).

I've managed to trigger it in some cases using the following steps:
1. Start Inkscape and open the attached
inkscape-effects_with_flowcharts.svgz
2. Ctrl+shift+d for document properties
3. Change the document width field from 1500 to 1400
4. Click the height field
...sometimes I just get some warnings, and sometimes it also crashes with
the attached backtrace.

(I occasionally manage to crash it by repeting step 3 and 4 with new width
values)

Could this be caused by a problem with our custom signal_value_changed for
the Scalar widget and unfortunate timing with the default signal for
focus-out on the Gtk::Spinbutton? A timing problem would explain the
randomness of this bug...
