One of features of lxde-base/lxterminal-0.2.0 are gtk3 support. Attaching ebuild patch, adding "gtk3 +nls" use flags... Reproducible: Always
Created attachment 397990 [details, diff] lxde-base/lxterminal-0.2.0 use: gtk3 +nls
gtk3 support is already in the tree now. In the future please provide separate bug reports for separate issues (in this case gtk3 and nls). The nls part looks incomplete, gettext should be optional. But I'm not sure I want to bother with making everything micro-configurable. If you feel there's a strong need for a -nls version please open a new bug.
