Sorry, I think I might have been ambiguous. It's the IDE which won't

When starting lazarus from console, do you get any error messages in the
console?
That was misleading, see the response :-(
Of interest are eventual error messages occuring when the application is
started in the IDE (F9).
This could be misleading, since one of the first things the program does
is hide the main form (i.e. the one that's malformed in the IDE) and
display a database login form in its place.
When I compile the program for GTK2 and start it (F9), I get what looks
like a konsole window appear with
Xlib: extension "RANDR" missing on display "localhost:11.0".
While I believe the message is benign, I don't know what's opening the
konsole session- I've not seen it in the past.
I also get an "Execution stopped" dialog(ue), plus an active database
login window (a custom form, not a built-in).
On the konsole session used to start the IDE,

If I fill in the database login form execution appears to continue,
despite the "Execution stopped" dialog(ue), with a form displayed which
should display data derived from a database on a server. However nothing
useful is displayed, and a diagnostic (coloured asterisk) suggests that
the background thread that talks to the database has done what's
necessary but then things have ground to a halt.
So in short, I think there are (at least) two separate problems here:
the first is an IDE problem affecting GTK2, and the second is a possible
thread/sync problem which affects both GTK2 and Qt.
I know it's unwise to say this sort of thing, but I have no reason to
believe that the application code is faulty: it's been running fine for
more than a year.
