First thank you for your effort!
I cant really guarantee that there are problems in my configuration (even
though I tried it with complete new users and on three indepently installed
machines), but I am afraid there are some (very annoying!) bugs left in kate,
at least in VI mode. I hope it can be fixed for wheezy.
This is the most important bug and the easiest one to reproduce. I hope the
instructions below are more clear.

I installed the debian package and debtags tells me all md5 sums are ok.

Open kate (even on a complete new kde user), alt+f2, type "kate"
klick close for the tipps
go into the menu and change the mode to VI:
settings -> configure kate -> editing -> vi input mode -> Use Vi input mode
press ok
insert following text (between ---) by pressing "i" and then typing the text:
---
a
b
c
---
leave the cursor at the very last position and press "v", then the up cursor
and then "D".
-> crash, new report attached (seems different then the last one). On another
i386 laptop I got the same crash report.
Expected behaviour: last two lines should be deleted.
best regards
