Indeed, if I arrange for the Qt client to quit normally (and hence refresh the rc file with per-topo tilesets), then this is no longer reproducible.

My S2_6 r33744 Qt client crashed on starting a new game, having popped up a "Map topology and tileset incompatible" error.

It looks like it might have re-entered the network processing code while it's put up the dialog, while not having got around to initialising the map?

This might be a symptom of an unusual freeciv-client-rc migration history -- I had run an old S2_6 build (r30297 from Oct 2015) earlier today (after having previously run recent S2_6), and noticed it doing some sort of client setting migration, so my rc-file might be a bit odd -- it doesn't seem to mention the per-topology tilesets, for instance, and has default_tileset_name="hexemplio", where it wants to start a server with WRAPX|ISO, so perhaps that's where the incompatibility arises. I don't know if there's a valid migration scenario from 2.5 which will have similar results.

I think I've seen other crashes associated with this error popup, without having done mad things to my rc-files.
