           Summary: Double superscripts causes kst to crash.
           Product: kst
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kst kde org
        ReportedBy: matt truch net

Version:           1.2.0_svn_trunk (using KDE KDE 3.4.2)
Installed from:    Fedora RPMs
OS:                Linux

Double super scripts cause kst to crash.  

I entered "s^-^2" as the text for the x-axis, and kst crashed.  This was while trying to figure out how to get s^{-2} (before I realized grouping was with curly braces, a la latex, duh!).  Double subscripts have a similar effect.  

Backtrace follows:

Using host libthread_db library "/lib/libthread_db.so.1".
`shared object read from target memory' has disappeared; keeping its symbols.
[Thread debugging using libthread_db enabled]
