- Steps to Reproduce set to new value
  Use an expression for symbol width that results in a negative number -- server should crash.

Use an expression like "100 + 100" for symbol width -- notice that width is drawn as 100 instead of 200.
- Defect Severity set to new value
  Medium
- Description set to new value
  The GDRenderer crashes if a symbol widht or height expression evaluates to a negative number. The math assumes width and height are always positive (and they should be).

Another problem is when parsing expressions that represent numbers. An expression like "100 + something" would erroneously be parsed to equal 100, because of the empty space betweem the 100 and the +.
