            Bug ID: 346547
           Summary: Kst crashes when typing the square bracket []
                    characters
           Product: kst
           Version: 2.0.8
          Platform: Compiled Sources
                OS: MS Windows
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: kst at kde.org
          Reporter: benlewis003 at gmail.com

Kst crashes when typing the square bracket characters into any text box that
supports the display of scalars, e.g. a label or axis label.

Examples of strings that cause a crash are:
[]
\[\]
\[V\]
Voltage \[V\]

Reproducible: Always

Steps to Reproduce:
1.Start a new Kst session
2.Create a vector with 10 samples from 0..9. Create > Vector > Generate > OK
3.Create a curve with the generated vector as both the x and y axis vectors.
Create > Curve > Place in New Plot > Ok
4. Save the Kst session, close and reopen the file. This step is important. It
does not crash unless this step is done.
5. Edit the bottom axis of the plot. Right click on plot > Edit > Labels >
Untick bottom label "Auto"
6. Enter the following characters "[]"
7. Crash

Actual Results:  
Crash

Expected Results:  
No crash

As a work around the required characters can be pasted into the text box. e.g.
pasting "\[V\]" does not cause a crash but typing it will.
