New Version 4.4.3 ImageSharp.UnknownImageFormatException

[LucaBastelt]

Describe the bug In one of our UnitTests we now get a SixLabors.ImageSharp.UnknownImageFormatException on parsing an msg file with a rtf formatted body. With version 4.3.2 this was not an issue.

To Reproduce Using the test msg file in 20 Testdokument Zeile 20.zip we use a simple new Storage.Message(MsgWithRtfBody);

Expected behavior The expected behavior is that the created message object has a filled BodyRtf property

Used Target Framework net6.0

I'll try to look into it tomorrow. I had to replace Microsoft MUAI with ImageSharp to fix another problem. I did not have any issues with my testcases so I have to figure out where this is comming from.

Thanks!

I would suggest to revert back to previous version as a temporary solution, it should work fine with .net 6.0 but gives reference errors with lower .NET versions because of a bug in MUAI

Fixed in the latest nuget package
