Summary 0010909: title_pooryurik_knight.png causes crash at start up
Description I build debug build and via gdb we found a problem, it is title_pooryurik_knight.png. I verified it.

What is interesting about it, it has different size of 512x512 px, while other title_image have 416x416px.

Resizing it to 416x416px fixes the crash for me.

Backtrace of the problem is added below.

// Win7 sp1, AMD/ATI HD6870 with latest driver

 Resizing this image to 416x416px is probably the simplest solution IMO.

 You can also crop it to... 511x511px (as example) - there will be no crash.

Also, for testing I tried to resize other title images to 512*512px size and game crashed in all cases.
