A user of our product that analyzes assemblies PDBs and source code, send us a assembly+PDB that contain source file paths that are not absolute file paths, like:
the string extracted for such a path is for example:
"/Users/XXXXXX/Documents/XXXXXXXMobileEstate/Apps/PlatformDemoApp-Mvx/PlatformDemoApp-Mvx.Droid/Resources/Resource.designer.cs"
In all the .NET stack so far PDB files only contain valid absolute paths (prefixed with a drive letter or UNC format)
