[rough-patches] crash recovery

[Alexander Kellett]

Over the last hour or so I started on a 
crash recovery system for Konqi, and well
it turned out to be quite a bit easier
to make a working version that i'd thought
it might :)

It's currently in the form of a konqueror
patch (konq_view.cpp), a simple konqi wrapper
and a ruby script.

0: make sure you've got ruby and kde debug build

1: Use "konq" to run Konqueror.

2: Intentionaly crash it, or if your really just 
   a plain unlucky person, go browsing for 5 minutes.

3: Run the ruby script (you'll need to change the ruby path)

Run "keditbookmarks /tmp/crash.xml", and notice the
crashed urls popup in the bookmark editor.

Simple, hé? ;-)

mvg,
Alex
