           Summary: GtkRadiant crashes when creating a cone brush with 100
                    sides
           Product: GtkRadiant
           Version: 1.5
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: critical
          Priority: P2
         Component: editor
        AssignedTo: gtkradiant at zerowing.idsoftware.com
        ReportedBy: david_costanzo at yahoo.com


GtkRadiant crashes if you try to create a "cone" brush that has 100 sides.  It
looks like GtkRadiant tries to display an "Assert Failed" dialog, but the
application goes away before that dialog can be displayed.  Based on the gdb
backtrace, the assert that failed is "radiant/brush.cpp:270 Final B-Rep:
inconsistent vertex count".

This may actually be two bugs.  The first is the crash.  The second is that the
application disappears without ever displaying the assert failure message box.

I am running subversion snapshot 5018.

Reproducibility: Always

Steps to Reproduce:
1) Start GtkRadiant.
2) Create a Brush that is 64 x 64 in the XY window.
3) Select "Brush -> Cone" from the menu.
   This displays an "Arbitrary Sides" dialog box.
4) Enter "100" in the "Sides" field and press OK.

What Happens:
GtkRadiant disappears.  If run under GDB, it raises SIGTRAP.

Expected Result:
Either a 100 sided cone is created or an error message pops up explaining that
100 is an invalid valid.


Here is the backtrace in gdb:
