QT 4.7: GdkPixbuf-WARNING **: Bug! loader 'png' didn't set an error on failure

[Astronomy]

Hi,
I have problem with Qt 4.7 qt-sdk-linux-x86_64-opensource-2010.05.1.bin under ubuntu 9.04 amd64 bit, with default buttons. The pixmaps are not beeing shown.

The file-open dialogs do not show the png for the open-butten, or in generall the png's for the directories, if i'm browsing through them..

regards Astronomy

From what I understand, there is a mismatch between the Qt libs and the pnglib on your machine. Looks like pnglib got updated by something and QT is now out of date.

Anyone have any ideas on when the next Qt build will happen?

My png version is: libpng-2:1.2.44-1.fc13(x86_64)

I have a devel version with the exact same version # on it.

I had similar errors during execution of an application inside QtCreator - custom icon theme for gnome caused problem - after switching it to default / standard ones everything's fine.

Hi,
sorry to writing to topic one month old, but i had this problem too and found a solution, so I think it will be handy for someone:

Just run as root:

update-mime /usr/share/mime/
update-mime-database /usr/share/mime/
gtk-update-icon-cache /usr/share/icons/YourTheme

Logout/Login and it will be all right now :-)

sudo gtk-update-icon-cache /home/kelvin/.icons/Faenza

sudo update-mime /usr/share/mime/
sudo update-mime-database /usr/share/mime/
sudo gtk-update-icon-cache /home/kelvin/.icons/Faenza

Hi I'm new to this forum. I've just tried the above and I'm getting the following error under Linux Mint. Any idea what I'm doing wrong?
