PowerPoint document with mailto links is destroyed by Aspose.Slides Open/Save

Hi,
When a PowerPoint file contains mailto links then a simple Aspose.Slides Open/Save destroys document. The file becomes 0 bytes long.
We are testing using Aspose.Slides version 18.5.0.0.

Attached are AsposeSlidesMailLinksIssue.zip that included the following files:

  1. OriginalWithMailLinks.pptx, the original document file from customer, that will get destroyed by Aspose.Slides Open/Save.
  2. WithoutMailLink.pptx, same as above except that mailto links are has been removed. This document file will not be destroyed by Aspose.Slides Open/Save.
  3. AsposeSlidesOpenSaveTest.aspx, code we use for Aspose.Slides Open/Save.

I really hope that You can help. In situations like this we need to protect our customers faith in Aspose.

Thanks and kind regards

@HIGHSTAGE,

I have worked with source files shared by you using Aspose.Slides for .NET 18.5 and unable to observe any issue. I have also shared my generated result with you for your kind reference. Can you please share sample project along with environment details so that we may further investigate to help you out.OriginalWithMailLinks12.zip (251.4 KB)

Thanks, I will try to boil the project down to a manageable size and post it for you. Meanwhile, maybe this stack trace can give you a clue:

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

ok, I boiled it down to a tiny C# console app. And the problem is gone if I use no license file (evaluation), like You tested. But if I add our Aspose.Total.lic license then the program crashes and the document is detroyed. I have attached a zip file with the project. I removed our license file since this is a public post, so You will have to add an Aspose.Total.lic license file in bin/debug folder. The test file is located in bin/debug folder. I hope You can reproduce.
Thanks and kind regards
