On a ~AMD64 sci-mathematics/wxmaxima-19.10.0 changes language all by itself as soon as one makes *any* change in the settings dialogue. Specifically, $ rm ~/.wxMaxima $ wxmaxima # Starts in English (correct + system default) $ # Edit => Configure => Enter evaluates cells => Okay => Close $ wxmaxima # Now starts in Portuguese $ cat ~/.wxMaxima | grep lang language=153 where 153 corresponds to wxLANGUAGE_PORTUGUESE_BRAZILIAN. My system is in en_GB and so there is clearly an issue here which causes it to write a bad config file. Switching the value to 59 (English) resolves the issue.
Tried to replicate it with (upcoming) 20.07.0 on ~amd64, the variable "language" didn't move from English (value 0). All available translations were built for this run.
