That was an extremely helpful backtrace, thanks Antonio! I have created a possible fix and would appreciate some testing as I'm having trouble re-creating it locally, see this ^

Thanks, I'm going to go ahead and merge that/cherry-pick. I'll wait on closing this issue until my other reporter responds later today.

Git commit c0f910a3439e30cb18b375f69ebc61574290caba by Joshua Goins.
Committed on 31/08/2024 at 17:16.
Pushed by redstrate into branch 'master'.

Do not reload accounts when initially setting the application proxy

This is quite the sneaky issue, but I think it goes like this:

1. NetworkController is initialized by the QML engine and it's
constructor is called
2. setApplicationProxy is called within said constructor
3. AccountManager's reloadAccounts is called, which in turn emits
accountsReloaded
4. accountsReloaded can trigger some signal handler in QML, in turn
making the QML engine initialize NetworkController again

Now setApplicationProxy has an optional parameter used by
NetworkController's constructor to prevent this situation from happening
in the first place.

Only emit reload accounts signal if they actually were

This should prevent odd situations where this signal was emitted even
though nothing interesting actually happened.
