           Summary: kate crashes on static word wrap
           Product: kate
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kwrite-devel kde org
        ReportedBy: hdevalence gmail com

Version:            (using Devel)
Installed from:    Compiled sources
Compiler:          gcc (GCC) 4.2.3 (Ubuntu 4.2.3-2ubuntu7) 
OS:                Linux

When I'm typing a line of text, and then later I go back and add to the text, \
extending it beyond the 80char limit, the parts at the end that should be bumped down \
to the next line go past the static word wrap limit, and instead of just breaking it \
into a new line, kate crashes.

Reproducible.

Here's a backtrace.

Application: Kate (kate), signal SIGABRT
