I'm using DotTrace 5.5.4, profiling a large WPF application on Windows 7, using Tracing and WallTime.
I run my app, start profiling after the app gets to the right spot. I click the button in the app which takes about 15 seconds. I then click Get Snapshot, it pops open the window which generates the snapshot, thinks for about 4 seconds, progress bar moves to around 80%, then I get the error: Invalid RVA's count in option header. Was able to do this 3 times in a row.
