Sounds like there is not enough applicaion heap to process the image. To be ignored?

4 000px × 2 248px * 32b = ~35MB of raw data to copied least twice in the memory. Yes, this is OOM. Since there is no mention of target device we can only assume limiting factor to be EPOCHEAPSIZE of Anomaly browser.

Closed since no further info was provided. Re-open with suggestions what to fix e.g. large images should be scaled down to small-screen/limited memory environment.

Issue is still reproducible. Pls check https://projects.maemo.org/bugzilla/show_bug.cgi?id=183631 for more details.

Please copy the details over here. Least I cannot access that bugzilla.
If the issue is on Symbian devices why the bug is in maemo.org?
And still as said, it is OOM and we cannot do anything radical about it as is. Image decoding is done in Qt and not in webkit.
Here is one related issue from Qt http://bugreports.qt.nokia.com/browse/QTBUG-14424.

Reporting hardware where the incident is seen is very crucial. When it comes to image RAM usage N8 using VG backend is very different beast than e.g. 5800 Express Music using raster backend.

Dint noticed the OS, As someone commented this bugzilla ID in Maemo bugzilla, i added the comments from that database.

As per your comments, I have moved the Maemo bugzilla error to Qt, so resolving this error as Invalid.
