ALso, the crash rate for this signature is virtually zero.  So if the cause is not found to be dropbox, then I would look to the list of open bug reports about crashes and attachments https://mzl.la/29S8XJS

Thanks for your support. 

I can now see in the crash report online the red icon (Ø) in the module tab as you pointed out. I was not aware of this tab nor that the report would highlight issue in such way, it is good to know.

Following your recommendation end-user has now removed Dropbox application from the computer, hopefully that will sort the issue, I am fairly confident it will.

If crash occurs again, I'll have a look at the resource you pointed out.

Thanks again for your help much appreciated.
