GtkText crash / bug

[Stefan Jeske <jeske braunschweig netsurf de>]

Hi Owen !

This time it was just a matter of seconds to get a sigsegv... 
I just selected about two or three pages of text and pressed 
Delete. Backtrace follows.

The other bug I noticed is : 
- Move the point to somewhere other than the first position.
- Press Cursor Up / Down.
- Press HOME.
- Press Cursor Up / Down.

The point doesn't stay at the first position.


Program received signal SIGSEGV, Segmentation fault.
