I checked it again with another window manager. Again, it's 
https://cgit.kde.org/labplot.git/tree/src/kdefrontend/datasources/
DatabaseManagerDialog.cpp#n48

with the icon "network-server-database":
 
alex@notebook:/usr/share/icons/breeze>find . -name network-server-database*
./places/16/network-server-database.svg
./places/22/network-server-database.svg

xporp for this dialog is:

The icon "network-server-database" is not shown in the window title bar. 
Killing kwin, starting openbox -> the proper icon is shown. Killing openbox, 
starting kwin_x11 -> application's default icon is shown. I don't know how the 
window managers are supposed to do the job here, but somehow openbox manages 
to show the proper icon despite the empty string 
_NET_WM_ICON_NAME(UTF8_STRING)...
