Aspose Cells .NET with MONO fails to open file with embedded image

Dear support engineers,

We have faced Aspose Cells for .NET (including the latest version) failing to open the file with .BMP picture in it. That only happens when running on Mono (on .Net all goes fine). Mono version used is: 5.8.0.103.

The code that fails is:
var doc = new Aspose.Cells.Workbook(inputFile);

The sample file is included. in.zip (33.0 KB)

Hello, Shakeel!

Thank you for the sample program. I tested sample files with it. The one that I attached earlier runs Ok, but I found some files that cause crash. I attached the zip with those files, along with stacktrace and debug output.
