Problems with Editor

[Midoron]

Hello all,

I can't start the map editor, it just quits after this output:

checking mode possible...

setting mode to 1280x960
locale could not be determined; defaulting to system locale

error display: could not open image 'terrain/off-map/wood.png'
Segmentation fault

Currently I use version 1.3.9+SVN, svn revision 21137, running on gentoo linux, but I have this problem for several weeks now.
I also have version 1.2.6 installed (for online games), both versions sharing the same config directory (~/.wesnoth), can that cause a problem?

Thanks for any hint.

That is pretty likely. You should always install different versions of Wesnoth in different folders/directories to avoid potential problems.
