Bug: Frequent crashes with print/export (System.AccessViolationException)

I'm getting fairly frequent crashes when using print/export. Unfortunately, the crash isn't writing an error message or call stack to the logs. But looking at Windows event view, I see this:

Application: Logos.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.AccessViolationException
Stack:
