This doesn't make a lot of sense to me.

The function GetNormalizedFullPath does not call FileIOPermission.QuickDemand, so I don't see how the stack trace could be generated.

In fact, I would expect this function to manipulate the path as a string and not to access the file system in any way, and not to check the file permissions.

This makes the error quite baffling.

I am looking at the source of SvnTools.cpp in my version of SharpSVN (1.12), which might differ from the version in SharpSvn 1.9. However, I don't think there has been any change in this function since about 2013, so that is probably not the explanation.

I propose taking no action on this issue, unless there is a new error report with SharpSvn 1.12.
