[lmi] GTK diagnostics

[Greg Chicares]

Lots of GTK diagnostics appear if I run lmi's GUI for pc-linux-gnu
in a fairly up-to-date 'bookworm' chroot...

lmipath=/opt/lmi/gcc_x86_64-pc-linux-gnu/build/ship; 
LD_LIBRARY_PATH=$lmipath:/opt/lmi/local/gcc_x86_64-pc-linux-gnu/lib/ 
$lmipath/lmi_wx_shared --ash_nazg --data_path=/opt/lmi/data 2>&1 |less

...and do some useful work, like loading an input file and running it.
I copy them below in case they're useful. Perhaps they're not: I've
been seeing them for years, and I see similar diagnostics with 'meld'.
