[GtkSourceView] Line numbers not showing on windows 7

Hi, I'm trying to use the GtkSourceView widget on windows.

I got the binaries from there, so it's version 3.0-1 build with mingw64.

http://rpmfind.net/linux/rpm2html/search.php?query=mingw64%28libgtksourceview-3.0-1.dll%29&submit=Search+...&system=&arch=

For the most part it seems to work, but line numbers and a few other 
things don't show correctly. When I set show-line-numbers to true
using gtk_source_view_get_show_line_numbers the gutter shows on the left 
but it's just gray. Here is how it looks:

That's julia code by the way, but most functions are rather 
straightforward calls to the library.

Any idea what's going on there? Is the last versions of GtkSourceView 
supposed to work on windows? Thanks!
