Dammit, I knew I saw this recently on a thread, but apparently I can't
search my emails :)  thanks for the link.

BTW, I think I found a way to avoid the oversize without subclassing
GtkScrolledWindow, which might even be a better fix for the original issue.

Interesting.  It doesn't surprise me much, as my patch should not fix
anything actually -- it doesn't even make sense.  I just ended up seeing
this change fixed the issue, but I have no clue why it would…

So I guess it's some kind of memory corruption or something, due to
either a bug in Geany, Scintilla or GTK, or in mingw itself…  I'll try
and see if I can track the issue down, but without Valgrind I'm afraid
I'll have a hard time…

Anyway, thanks a lot for the infos, it'll probably avoid me heading in
the wrong direction :)
