Follow-up Comment #2, bug #25155 (project wesnoth):

I think 200x1 is okay because the mini-map's portrait-style aspect-ratio means
that the calculation for the mini-map's height stays at least one. But in
1x200, the mini-map's width is calculated (and probably rounded) to be zero.

Follow-up Comment #1:

Confirmed. It's not necessary to resize to 200x1 first. That one seems to be
okay, but resizing to 1x200 causes the crash.
