Please report any problems you experience with clear and complete information, including steps to reproduce, software and system information, and where possible, an isolated example patch and crash log.

Without such clear and complete information, it is less likely we will be able to.

• Summary: Provide a descriptive summary of the issue.
• Steps to Reproduce: In numbered format, detail the exact steps taken to produce the bug.
• Expected Results: Describe what you expected to happen when you executed the steps above.
• Actual Results: Please explain what actually occurred when steps above are executed.
• Regression: Describe circumstances where the problem occurs or does not occur, such as software versions and/or hardware configurations.
• Notes: Provide additional information, such as references to related problems, workarounds and relevant attachments.
