Looks like a bug in Qt painting code.
It is very unlikely that this is a Qt bug as this crashes in malloc, but allocation of an image sized 25x25 should never crash. One reason could be corrupted memory lists, but we cannot see where that corruption occurs. I think there was a GNU libc bug that could lead to memory corruption, but I am not sure which versions where affected by this bug.
