Comment 1 Oliver Putz 2008-01-25 15:12:01 UTC

I can reproduce this bug (kdebase rev765071). My normal Backtraces look like the one already posted, so I'll only attach a Valgrind output for this crash. (I hope it contains some useful information, as valgrind itself seems to have run into some troubles at the end...)

Comment 2 Maksim Orlovich 2008-01-25 19:32:06 UTC

Ugh. Somehow libPNG tells us that an image is 8-bit per channel, while it is 16-bits per channel !?

Comment 3 Maksim Orlovich 2008-01-25 20:20:41 UTC

Created attachment 23278 [details]
Fix

Ugh. My mess up. The code was losing track of itself adding an alpha channel to
gray scale PNG with tRNS chunk

Comment 4 Matt Rogers 2008-01-25 20:58:01 UTC

Thanks. Will test over the weekend and report back.
