I've installed IV from the centos repository. test.exr crashes
test_small does not crash but display weird colors: the RGBA layer is blue.
There's a mixup somewhere in the channels: if you look at the RGB
channel in single channel mode, they all look almost the same, so the
RGB layer shouldn't display so much blue.
I think i know why it doesn't work: when displaying in RGB or RGBA mode,
IV shows in the status bar which channels are displayed.
By default RGBA(0-3). I guess it's packing channels using the order in
the file, which is definitely not the correct one, as OpenEXR sorts them
alphabetically.

Yes, I was referring to opening them with iv. Sorry for being unclear.
I opened both using exrdisplay (a small tool to view an exr) and
Clarisse (through OIIO), they display fine. All channels seem
correct. (i'm on centos 6.4). It's definitely an issue with IV.
I don't know how IV works regarding graphic ram, but given the small
size of your image I don't think that's the issue.
Ok. Thanks for checking. Do you have an iv to test?

Hello,
I am currently playing with iv and found that it crashes pretty
often with exrs, which have multiple layers. I *think* it may have
to do with the graphics ram available, because smaller images/less
layers tend to work. But also those smaller images sometimes look
really different, the colors are totally off (see screenshot).
Checking the exr in nuke, it seems they are totally fine. I am
testing with current master on CentOS 6.5 and Windows 7. Please find
the links of the images below (they are pretty small). Can someone
open them correctly and with what configuration?
