Ahoy everybody,

After upgrading to SailfishOS 1.1.1.27, my app fails to start sometimes (~ 50%),
the cover page appearing shortly (~ 3s) with a spinner, then disappearing again.
When trying again after failure, it usually works fine.

In journalctl, I get these messages when the error occurs:

-----

A user has reported problems with starting the app also, and I don't see this
happening to other applications, so I assume there must be something wrong with
mine. Any ideas how I could track down the problem causing this? I cannot
reproduce this behavior when running from the IDE.

Note: I am quite new to Qt, so there are good chances I am missing something
obvious.

Thanks in advance,
Jens
