--- Comment #1 from RJVB <rjvber...@gmail.com> ---
A bit more info on this one: apparently the debugger toolbar state is saved in
more than 1 location. If it reappears against my instructions, I quit KDevelop
and turn the debugger toolbar off in kdeveloprc, it will reappear consistently.
In Sublime::MainWindow::loadSettings() its visibility will be set to false,
which also allows me to set a conditional breakpoint in QWidget::setVisible()
to catch subsequent changes. And indeed, a bit later I get a whole series of
hits with the backtraces below, suggesting that its a plugin restoring its view
settings that causes this. Could that be the debugger plugin itself or is it
just the plugin load order and what its idea bout debugger toolbar visibility
is that determines whether it will ultimately be visible?
If so, why do so many plugins store a visibility state for this toolbar, and
what can be done about it? This basically means that the toolbar's effective
visibility at startup is almost purely random, and that doesn't apply for other
toolbars.
