Description warxcell 2012-03-03 21:39:01 UTC 
Hello.... gwenview freezes for 10-20 seconds after closing it. I can move my mouse but can't do anything else during these 20 seconds. No real errors. 
My machine is: 4GB RAM, 2.6 GHz Intel Core2Duo, 512MB nVIDIA GeForce 5200GT.

This is the output in console.

Comment 3 Benni Hill 2013-03-18 16:38:37 UTC 
Can you check (e.g. with htop) if gwenview (or kio_thumbnail) is using the cpu while this freeze occurs?
Does this freeze occur every time when you quit gwenview (also when you quit it right after startup)?

@Bojidar Hristov: Is this reproducible with newer versions (>=4.9.1)?
Comment 4 DrHouse 2013-03-19 13:58:49 UTC 
I make request to stablize libpng-1.5.14 because it  fixes a bug in handling compressed iTXt (international text) chunks

So the bug only appears when gwenview/dolphin (or kio_thumbnail) is dealing with pngs?
