Comment 1 Milian Wolff 2010-09-27 21:57:01 UTC 
will look at it later, but could it be that you have kate installed from sources? i.e. the one that does not implement the smart itnerface anymore?
Comment 2 iamsunilk 2010-09-28 03:23:09 UTC 
Dear Milan,
My version of kate is installed from ubuntu ppa repositary
Thanks

Comment 3 Milian Wolff 2010-09-28 12:38:05 UTC 
ok, no assert since its a release build, so this is actually a duplicate.

If you can reproduce it at will, you should do some debugging with GDB to find out why there is not smartrange for this document...
