Cannot open emails in Evolution anymore - update problem?

As of late, I cannot see/open any emails in Evolution (under XFCE) anymore.
When I try, I get the message that a “WebKitWebProcess” crashed, when attempting to
display the message. Restarting the computer did not help.
I presume that the problem may be caused by yesterday afternoons
update of “webkit2gtk”, but this is only a guess.
(according to /var/log/pacman.log, the package is updated roughly once per month, so it would
be appear as a slight coincidence, if there was no connection)

Any suggestions or is this problem known? (I could not find anything actual)
