[Svetlana Tkachenko]

GNUMail starts with

2019-06-01 06:59:33.831 GNUMail[21423:21423] styleoffsets ... guessing offsets
2019-06-01 06:59:33.834 GNUMail[21423:21423] styleoffsets ... guessing offsets
2019-06-01 06:59:34.014 GNUMail[21423:21423] Bad application class '(null)' specified
2019-06-01 06:59:34.531 GNUMail[21423:21423] Problem posting notification: <NSException: 0x56399701e850> NAME:NSInvalidArgumentException REASON:[NSURL initFileURLWithPath:] nil string parameter INFO:(null)

But after this, when I click preferences, there is no additional console output.
