Bug #4477	MA reports PRIMARY KEY indexes as allowing NULL values

Category:	MySQL Administrator	Severity:	S3 (Non-critical)
Version:	1.0.6-beta	OS:	Linux (Debian Linux)
Assigned to:	Alfredo Kojima	CPU Architecture:	Any

Description:
When viewing the catalogs information section, if you go to the indexes tab, then it will list PRIMARY KEYs as Null Allowed = Yes.  Indexes that do allow NULLs for real will have nothing in that category.  Basically it looks like it is reversed.  This same bug was reported in earlier versions of the Windows MA as BUG#2851, but wasn't present in the Linux version at the time.

How to repeat:
1.  Run MA.
2.  Go to Catalogs option.
3.  Click on Indexes tab at top.
4.  Select a database.
5.  Notice all of the primary keys say they allow nulls.

Suggested fix:
Fix whatever was done with the Windows MA to make it work.
