           Summary: crashes after opening non-utf8 files
           Product: kdevelop
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-bugs@kdevelop.org
        ReportedBy: trigger@space-based.de

Version:            (using KDE 4.2.96)
OS:                Linux
Installed from:    Compiled From Sources

I'm currently using kdevelop r995594 and can trigger a crash like this:
a) close all open files
b) Open the attached file. You will get a message that the file is non utf8 and
will be opened read-only.
c) Close the dialog
d) CRASH

The backtrace looks like this:

Application: KDevelop (kdevelop), signal: Segmentation fault
