Description:
Sporadic exceptions observed when creating new Schemas.

Same sequence repeated several times produced errors inconsistently.
This was observed across multiple executions of the program.

How to repeat:
- Select "Catalog" icon
- Right Click -> Create new Schema  -> Schema Name: "dvt-test"
- Click on schema "test-bug"  -> "null pointer exception"

Suggested fix:

Coding Suggestion:  Past experience with Delphi coding suggests a variable initialization or cleanup problem. This is typical of local stack-based variables which assume unpredictable values. Explicitly nulling deallocated pointers/objects may show the problem more consistently.

I wasn't able to repeat with version 1.0.6.
