Synaptic filter serious bugs

[Rastko <lylecorman@gmail.com>]

Hi,

When browsing through Synaptic custom filters, 

the right-hand side didn't reflect the selection on the left.

(eg. same checkbox set for diffrent filter name selection)

When i clicked OK, the filter actually changed to what was
displayed, but that was completely wrong!

After selecting a few of them to figure out if it will become
sane again, the program crashed.

Also, when selecting the "Set Internal Option", the program 
always crashes.

This is a very concerning behavior of a program like a 
package manager. Something's horribly wrong here.
