Selecting a dive from the list (and seeing the one I selected) seems to work for me.</div>

New versions of Subsurface-mobile (4.6.3.228) should now be available to our testers both on iOS and Android<br />

It seems that these crashes started with the move to Kirigami 2 and<br />

Quick.Controls.2 - but since they are somewhat hard to reproduce, I'm not<br />

100% sure.<br />

<br />

I have been able to create one scenario where I can trigger the crash<br />

reliably under a debugger, and the stack trace doesn't really tell me<br />

much.<br />

<br />

We appear to be loading all of our code and based on the debug output we<br />

are just about to show the UI when things crash.<br />

We seem to be crashing deep inside the destructor of a Delegate which<br />

appears to be a QQuickAbstractButton.<br />

<br />

Marco - does this tell you anything more useful?<br />

<br />

I'll be happy to try some things now that I can reproduce the crash.<br />

<br />

Thanks<br />
