[ShowImage] crashes in conversion::convert_from_CMYK_to_32

[diver]

This is hrev40208, gcc4hybrid.

If I close ShowImage quicky after opening 2,7mb photo it crashes.
If I open the same image and wait several seconds before closing it - then it closes without crashing.

I copied this image to another folder and now ShowImage doesn't crash anymore.
I copied second image to the same folder and crash reappeared.
Then I deleted both of them and copied yet another image to that folder - no crash. Then I copied /boot/system/data/artwork/HAIKU logo - white on blue - big.png to that folder and reappeared again, but only after opening and quickly closing HAIKU logo - white on blue - big.png file.

Looks like something is wrong with background preloading of big images.

Haiku revision: hrev42211 not a bug. I have tried it over 4mb image files and there was no problem to close . System: Haiku hrev1-alpha3 on VMware workstation 8 on windows 7 32 bit

(GCI-2012 Participant) Haiku revision: hrev44702. Not valid, I have tried with duplicates of an image 5.81mb big and it does not crash even when closed quickly. System: Haiku R1-alpha4 on Virtualbox 4.1.20 on windows 7 64 bit

For the crash to happen you need a CMYK JPEG picture in the folder it would seem (or else I don't see how you would end up with that backtrace).

I found one such file: ​http://upload.wikimedia.org/wikipedia/en/2/25/Channel_digital_image_CMYK_color.jpg

Currently ShowImage doesn't render it at all. Qupzilla and Web+ do.

Mh, I tried that image again and now it displays just fine. Could have been a problem with my installed system then. No crash with it in any case.
