Inkscape crashing when setting blur to 0 on drop shadow

[rickmastfan67]

Inkscape 0.48.5 r10040
Windows 7 x64 SP1

Steps to reproduce:
1. Load attached SVG file.
2. Select the object in the middle of the screen.
3. Filters > Shadows and Glows > Drop Shadow
4. Change the 'Blur radius' to 0. (don't mess with the other settings)
5. Now, click 'Apply'.

What should happen:
Inkscape should render the drop shadow completely without any problems.

What happens:
Inkscape encountered an internal error and will close now.
Automatic backups of unsaved documents were done to the following locations:

Inkscape crashes about 99% of the time following the steps above. However, there was just one time that it didn't crash when following the steps above.

Inkscape also crashes if you replace Step 5 with clicking the 'Live Preview' box. However, you don't get the emergency save to trigger if you were following my steps above exactly.

This could be related to the fix from Bug #808013 that was put in the 0.48 branch.

Interesting note here, but if you reload the 'emergency save' file in Inkscape, the drop shadow renders most of the time (there was a few times that Inkscape crashed on opening the 'emergency save' file).

Since the settings are stored per user, could you please shared the "other settings" we are not supposed to mess with? (You don't mention that resetting the prefs to default is part of the 'steps to reproduce', so I assume the other settings are based on your earlier applications of the filter effect).

I forgot to mention this, but I can duplicate this with a completely fresh preferences and my normal Inkscape preferences. So, it shouldn't be a profile bug.

Anyways, the settings that the fresh preferences set are:

Blur radius, px = 2.0 (this is the only one I change to trigger this bug on my system)
Opacity, % = 50.0
Horizontal offset, px = 4.0
Vertical offset, px = 4.0

And I just tried Inkscape 0.91pre3 r13670 x64 with the a fresh preferences settings and it didn't crash. So, it seems that it's restricted to just the 0.48 branch.

Now, I know that odds are that there will never be a new 0.48.x released since 0.91 is very close to being released, but still, if there is, I hope this would be able to be fixed in it if possible.
