Description Ernst Bachmann 2003-03-07 15:06:55 UTC 
Version:            (using KDE KDE 3.1)
Installed from:    Gentoo Packages
OS:          Linux

when clicking on a large (5000x6000 pixels) png file in konqueror (file browser mode), it attempts to view it in it's embedded image viewer.
Now that viewer tries to allocate a XPixmap of that size (I think). The X-Server now tries to allocate ridiculous ammounts of memory, causing the kernel to kill it (If i got luck) or bringing the complete system to a halt.

Opening that file with kuickshow produces the same effect, so the bug is probably not located in konqueror, but in the kde libs or QT.

Possible solution: add a configuration option to limit the maximum size of an XPixmap the kde libs (or QT) will try to allocate.

large png file

this png file causes my 256MB box to crash. (5000x6000 pixels, all white)
The file I first noticed the bug with was created by xpertmud (a KDE MUD
client), which needed about 1GB of Ram to save it (using KImageIO, I think),
but it was >2MB, so I couldn't upload it here.
