Nixnote2 exits when network gets disconnected

[andruska]

I have configured Nixnote2 so that when you minimize the Nixnote2 window, it stays visible only in the system tray. So, when network get disconnected and no Nixnote2 window opened but only icon visible on System Tray and Nixnote2 attempts to sync, it just crashes.

Can anyone reproduce this ?

BTW: Nixnote2 is far better to work with, than with original Android app or web interface.

I reproduced problem now this with log information.

Nixnote2 crashed. And that way it behaves every time. Behaves exactly same on other tested computer.

When leaving window open and not minimizing to system tray, or if window minimized to xfce4 panel window button, the crash is not present.

It looks like a normal exit, because the retcode is 0.

[andruska]

Behaviour definitely is not normal. It doesnt let to work offline.

[boo-yee]

The reason of issue is: when the last window is closed, the Qt application will exit automatically. This is a feature of Qt. I have created a pr to fix it. You could disable the auto sync in the preference dialog temporarily.
