Description Paul 2015-10-12 08:12:35 UTC 
Adding a Convolve Matrix effect to an object then increasing the kernel size property causes there to be garbage values in the filter kernel.  Trying to change them result in other values in tthe filter changing or eventually the application crashing.

Reproducible: Always

Steps to Reproduce:
1. Create an object of some sort
2. Select Filter Effects Editing tool
3. Click View and Edit Filter
4. Select Convolve Matrix
5. Click Add Effect to Current Filter Stack
6. Select feConvolveMatrix
7. Increase Kernel Size
8. Click Edit Kernel

Actual Results:  
Various fields in the kernel will have nonsense values, modifying them may change other fields or crash the application.

Expected Results:  
Fields initialized with some reasonable values, not crashing.

Seen also in 2.8.5 (Gentoo) and 2.9.6 (Netrunner Linux VM).
