When generating colored text using a '\colortbl' in a RichTextBox, the
following method works fine on Windows, but fails on MacOSX 10.6.2 with Mono
2.6.1 and 2.6.3.  It also generates the same results on Linux with Mono

See this link for code to reproduce the problem:


The error shown in the terminal is this:

RTF Parsing failure: Malformed color entry
RTF Stream Info: Pos:324 Line:1
TokenClass:Text, Major:8, Minor:0, Param:-10000000, Text:

The RichTextBox remains blank when the error is thrown.  Program does not

The error appears to be generated in System.Windows.Forms.RTF.ReadColorTbl()

Reproducible: Always

Steps to Reproduce:
1.See sample code at Stackoverflow.com link.
2.Pass in a RichTextBox control and any text to reproduce the error.
Actual Results:  
Rather than populating with colored text, the RichTextBox remains blank.

Expected Results:  
The RichTextBox will show text in one of the colors listed in the color table.

If you would like to run the application that produces this error, you can
download it here:


To generate the error using this app:
1. run the start.sh file in a terminal window.
2. Click File --> New.
3. Click the next to last icon in the toolstrip, a set of gears that shows the
tooltip "Edit Area Settings".
4. Type anything in the "Area Name" text box.  The terminal will show the
'malformed color entry' errors.

I can provide source code if needed, but the only RTF code that executes is at
the Stack Overflow link above.
