Version: 1.6.3 (using 3.5.8, Debian Package 4:3.5.8.dfsg.1-6 (lenny/sid)) Compiler: Target: x86_64-linux-gnu OS: Linux (x86_64) release 2.6.24-rtoi-rc5 I started krite, created a new 1024x768 transparent image using RGB. Then I tried to load a png file using the recent list and krita crashed with SIGSEGV. See BT below. Using host libthread_db library "/lib/libthread_db.so.1".

Created attachment 23327 [details] Png image tried to load.
Hi, I can't reproduce :/ The backtrace show something deep into Qt. A few questions : * Is the crash reproductible ? * Does it happen when loading the file using the file dialog of "Open Existing Document" ? * Does it happen for other png files ?
Created attachment 23328 [details] Valgrind log. Not reproduced. I tried getting a proper valgrind log of the crash, but I couldn't reproduce the problem.
*It is 100% reproducible when running without valgrind. *I don't know exactly which option you mention but once I created the transparent blank file and I could see it I chose: File->Open recent->preview.png *Haven't tried yet. Thanks for the fast response.
The valgrind output shows a lot of horrible things, but still nothing related to png loading :/ For the second question I either meant using the file menu open "File > open...", or the button on the bottom left labeled "Open Existing Document"
Created attachment 23357 [details] kritarc file. Well now we know some more clues. If I remove the kritarc file and retry I the crash is gone. I'm attaching my kritarc in case it is helpful to catch this ugly bug.
I can't reproduce on krita2 beta2 nor 1.6.3, either by using attached kritarc
Indeed no crash here (something strange happening to my dockers, but no crash!)
