Public bug reported:
I have a png image with a size of 8580 by 6000 pixels. The file is about
83MB in size (I know, the image uncompressed into memory is much bigger,
should be in the order of 147 or perhaps 196 MB; not that much,
anyway).
I can usually view and handle it easily with Image Viewer: zoom in, zoom
out, move around, without issues. I never modify and save it from within
Image Viewer, I just use it to view it.
Every once in a while, I close Image Viewer, I regenerate the image, and
I open it again in Image Viewer.
Everything works fine for a few times.
Then suddenly, when I have already opened the image and zoomed in and
out and moved around a few times and it seems to be working just fine,
the "loading" progress bar shows up on the bottom right corner of Image
Viewer, as if it was reloading the image (though it has NOT been
modified); the progress bar gets stuck around 18% or so, and the program
becomes completely unresponsive, and the whole system does.
It looks like Image Viewer suddenly starts eating up a lot of memory, causing
thrashing. It's the typical symptoms.
The system won't respond to clicks and keystrokes (the mouse cursor does move,
but jerkily).
So I can't even close Image Viewer or switch to a terminal or virtual console
and kill it; the only thing I can do is to physically power off the computer.
The last part is a more system-wide bug in Ubuntu (an OS should never,
ever stall unrecoverably because of the misbehavior of a single program,
no matter how bad), but the fact that Image Viewer suddenly begins
eating up memory exponentially (or whatever it is that it does causing
the system collapse) is certainly a bug in ImageViewer, and a critical
one.
It happens SYSTEMATICALLY after a few times I open and close the image.
I can't tell if it's systematically after a given number of times, but
sooner or later, it will happen, guaranteed. I have already rebooted
with the hardware button like 5 or 6 times in a few hours because of
this.
