           Summary: sigabrt pressing tab in misformatted source file
           Product: kdevelop
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: gideon
        AssignedTo: kdevelop-devel at kdevelop.org
        ReportedBy: sergico at libero.it


Version:           3.0.0 (using KDE KDE 3.0.3)
Installed from:    Compiled From Sources
Compiler:          g++ 2.95.3 
OS:          Linux

I can reproduce the crash. 
Opening more than one source files, NOT in a project, some file had the lines not correctly indented. I moved on one of this line and press tab to reindent correctly the line/s but the curson disappered and after some seconds, the application crashs with sig 6.
The indent style was set in the preferences to ANSI

All default plugins loaded exept "File Selector"
