• Fixed issue that affected some SVG files from being identified correctly.
• Fixed issue that could lead to a crash when using an invalid policy schema in Word Search.
• Fixed issue affecting PDF files where a partial policy file led to a processing failure rather than falling back on default policy.
• Fixed issue where some GIF files had remedy items reported with '0' IDs.
• Fixed issue that could lead to a crash when processing some BMP files using the Python wrapper.
• Fixed issue that could lead to a crash when processing some SVG files.
