           Summary: kate crashes when using vi-mode '.' command
           Product: kate
           Version: unspecified
          Platform: Archlinux Packages
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kwrite-bugs-null@kde.org
        ReportedBy: dimsuz@gmail.com


Application: kate (3.7.1)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.4
Operating System: Linux 3.0-ARCH i686
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I was doing the following: in normal mode cursor was at the beginning of the
word "trades", I pressed "cw" and changed it to "account_trades". Then I went
line down to the another word "trades" and pressed '.' to change it similarly
to "account_trades" by replaying my change. Kate crashed.

This crash happens not always, but very often, I'm even kinda afraid to use '.'
command :-)

Kate is compiled from git branch '4.7', KDE packages are from ArchLinux,
version 4.7.1

-- Backtrace:
Application: Kate (kate), signal: Aborted
