crash when saving after changing stroke width (no focus-out-event)

[uwestoehr]

- open the attached SVG file in Inkscape 0.48
- select the straight black line (arrow) in the middle
- open the fill and stroke dialog and change in the Pattern tab the width from 0.7 to 0.6 (and do nothing else (not pressing OK or anything!)
- save the file (via Ctrl+S)

result: CRASH

I created the SVG-file with Inkscape 0.48 on Windows.

(inkscape-bin:21676): Gtk-WARNING **: GtkEntry - did not receive focus-out-event. If you
connect a handler to this signal, it must return
FALSE so the entry gets the event as well

Same issue when clicking on one of the buttons in the snap controls bar, also affects the opacity slider at the bottom of the Fill&Stroke dialog:
