This bug tracker will shortly be moving to Github. As part of this process, we are reviewing old bug reports on gna.org.

This bug was marked as "Ready for Test" or "Works for Me" some time ago, but was still classified as Open and no feedback has been submitted since then. I am therefore assuming that the problem has been fixed to everyone's satisfaction (or was't reproducible by anybody else).

If you believe that this bug still affects the most recent git master of MyPaint (and thus the next release), please feel free to open a new issue on
Github about it. Our new issue trackers are:

Okay, this image loads fine in MyPaint 1.1.0 on Linux. Maybe the problem was fixed, or it's Windows specific. Would have to test with one of tumagonx' more recent experimental Windows builds...

Can you share the file "C:\Varfiles\var_info\infocache\ic-20140523\images\p_img7.png"? Or get more info about it. Or, as a workaround, open it in another program (e.g. GIMP), convert to RGBA, and save.
