This look like a race condition:
* Sometimes it works, sometimes it does not.
* The behaviour is independent of the email, ie. using the same email it sometimes works and sometimes fails.
* Even opening a mail and repeatedly clicking the same link contained therein will alternate between opening the link and causing the error dialog.
Just for reference: My machine has an SSD, in case there really is a race condition which could be influenced by disk perfmance.
