The languages need to be put in appdir/data, e.g.bin/data/locale.

The icons weren't loaded because the svgiconengine plugin was in the wrong place: it should be directly underneath the exe, not in a plugins/ subdir.

Dumb question, but how exactly are mingw debug builds supossed to be used, @rempt, @stefanobonicatti, @abrahams ? Then I can write something down in the manual about that.

Unzip, and then double-click on bin\krita.exe. No runtime installation is necessary. I probably should add the krita desktop file that we have in the root folder for the msvc builds, though.

will it then generate a backtrace?

A full mingw environment install includes a Windows port of gdb, I remember using it with success when I attempted mingw builds a while back. I have not tried using Breakpad.

I also don't remember whether debugging logs go to stderr or if you need to use dbgview.

I probably should check, I did get a backtrace in stderr, but that was when I managed to trigger a crash when running under wine.
