Description Andrey Cherepanov 2007-05-16 09:56:51 UTC 
Version:           1.6.2 (using KDE 3.5.6, ALT Linux i586)
Compiler:          Target: i586-alt-linux
OS:                Linux (i686) release 2.6.18-wks-smp-alt2

I try to save small .kra file as PNG file. Krita hangs up and eat all available memory. Saving in GIF is ok.

Try to save in PNG file with transparency.
Comment 2 Halla Rempt 2007-05-16 10:11:54 UTC 
Hm, I'm afraid I cannot reproduce this bug.
Comment 3 Cyrille Berger 2007-05-16 10:41:36 UTC 
You need to upgrade your version of libpng.
Comment 4 Dmitry V. Levin 2007-05-16 14:53:49 UTC 
What libpng version is required?
Comment 5 Cyrille Berger 2007-05-16 15:12:33 UTC 
Either from 1.2.0 to 1.2.9 or from 1.2.15 and higher (but no libpng between 1.2.10 and 1.2.14)

Note that, I haven't test 1.2.16 to 1.2.18, but the bug was fixed in 1.2.15.
Comment 6 ALeXeY 2012-07-10 08:57:54 UTC 
libpng 1.2.46-3ubuntu4
this bug (or similar) is present, at least when saving 16-bit png
Comment 7 Halla Rempt 2012-07-10 12:38:20 UTC 
Ok, let;s investigate again.
Comment 8 ALeXeY 2012-07-10 13:06:46 UTC 
May be I was wrong and it is export bug. The bug appears when export (may be not just png...)app
Comment 9 Sven Langkamp 2012-07-10 21:34:30 UTC 
I also have 1.2.46 and I don't see any big increase of memory usage. Only a small temporary bump while saving.
Comment 10 Halla Rempt 2012-10-09 14:10:38 UTC 
I have 1.2.49-2.1.2 and 1.4.11-2.5.1 on opensuse 12.2. I do see an increase in memory after exporting with png.

I've saved a few dozen png's when running under massif, and no leak anymore.
