Comment 2 for bug 1523153

When select theme priscilla:

SSERT INFO:
../src/generic/imaglist.cpp(66): assert "(bitmap.GetWidth() >= m_width && bitmap.GetHeight() == m_height) || (m_width == 0 && m_height == 0)" failed in Add(): invalid bitmap size in wxImageList: this might work on this platform but definitely won't under Windows.

I have tried to copy theme files from stable but same result.
