Sudden C++ assertion "image.IsOk()", for which reason?

Hello,

I just had this:

  self.sortctrl0.SetBitmap(images.updown.GetBitmap())

fail with

  File "wx\_controls.pyc", line 73, in SetBitmap
  PyAssertionError: C++ assertion "image.IsOk()" failed at ..\..\src\msw\bitmap.cpp(820) in wxBitmap::CreateFromImage(): invalid image

after displaying this bitmap in several controls thousands of times.

Following in my logfile I have about 100 pages of asserts:

What could possibly have gone wrong?

Sounds like the image file somehow got corrupted, but I have no idea why.
