Lotus Notes Client crash ntdll.EtwEventEnabled - lotus-notes

Question

Lotus Notes Client crashed for one of the user few days back. After that we had him install the Lotus Notes twice but the issue continues. PLease find the NSD below. It shows ntdll.EtwEventEnabled at the top of the stack trace and Access Violation as the error message but I am not able to find the resolution.

Based on the stack and the version number it appears to match SPR EZEL6XZ5S3. This was where Notes 6.5.3 & 6.5.5 would crash on Vista (clicking the mail icon on the welcome page).
At the time of the creation of the SPR neither versions were supported by Vista (may have changed in a later fixpack).
It was never investigated further in R6 and moved to R7/R8 where it was found to be not reproducible.
Based on this I would recommend to install the latest fixpack for that release. However R6 is end of life, so if that does not resolve the issue then the only other solution is to upgrade to a later supported release.
I see no other reports of the stack.
