           Summary: [SVN 633671]: Crash creating equation f(x) vs. x
           Product: kst
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kst kde org
        ReportedBy: dwiebe physics utoronto ca


Version:           1.4.0_devel (using KDE 3.5.4, compiled sources)
Compiler:          gcc version 3.4.6
OS:                Linux (i686) release 2.6.17.8

kst crashes while trying to create an equation.  Reported on the console:

kst: FATAL: Thread -1239570752 tried to write lock KstRWLock 0x856b03c while holding a read lock


STEPS TO REPRODUCE:

1. start kst
2. New Vector Dialog: Name=x, Source=Generate
3. New Equation Dialog: Equation=[x], X vector=x

Crash occurs upon hitting OK in the New Equation dialog.  The crash appears to be related to plotting equation-involving-x versus x.  Plotting equation-involving-x versus another vector, say y, doesn't produce the crash.
