Can not confirm on Win7/64, latest build, nor 2.70a official. Tried several directories with different images and image formats.

Can you narrow the problem down to certain images in the directory?

Can not confirm the crash on debian 64bit. Does the crash happen with any image in the folder or it only happens when having specific file/image in the browsing folder?

  1. I didn't try this on Windows, so can't say anything about this.
  2. I found that the problem is not image specific. Blender crashes anytime I try to press Thumbnail view while opening file of ANY type (for example press F1 and try to turn on Thum view). Maybe the case is my Linux environment specific. For example I read recently, that transition to Python 3.4 in Blender is just started, but in ArchLinux upgrade to Py 3.4 has already been for a while.

Maybe not fully related, but in the thumbnail part, in thumbs.c the escape_uri_string() function at line 166 can cause a crash because the len variable counts the length of the p array instead of q (ie. buffer overflow).

@Igor Valorin (igvalor2), Blender works just fine with Python 3.4x on Arch Linux (Im using it here), the translation is mainly for the default build configuration and our releases.
