Backtrace from one of the application crashing(krita)

As the title said, many KDE applications crash when accessing a bmp image with
an alpha channel. bmp images with no alpha channel seem to work fine.

Step to reproduce:

1. Open Gimp, create a new image with a transparent background. Paint hello!
Export to bmp using the following Advanced Settings: A8 R8 G8 B8.

2. Try to load the file using any of the following:
- Krita
- Gwenview
- Okular

3. It should have crashed.

More information:
I first notice the bug after having installed the game Capsized from the Humble
Indie Bundle. The game install its own link under the KDE Game menu. The link
points to a bmp file under ~/capsized/Capsized.bmp. While trying to launch
Capsized from the KDE Game menu, my desktop would crash. When trying to edit
the KDE Game menu link using kmenueditor, it would crash when I would click to
modify the icon(as the icon in the link points to that bmp file). Trying to see
the image using Gwenview or Krita resulted in crashes. Traversing a folder with
this type of bmp file will cause some other applications, such as the bug
reporting tool when trying to save a report to disk, to crash as well. Trying
to view the image with Gimp worked fine.

This is my first time using this bug system, the KDE tool wouldn't let me post
because of missing "Kubuntu Packages" or some such. Let me know if there is
anything missing. I can provide backtraces from other application than Krita
since many of them crash.
