Too large PNG export hangs everything

[Magnes]

When you try to expoert a huge PNG by mistake - It happens to me sometimes when I hit export without checking "SELECTION" and instead export the whole drawing at high DPI - Inkscape hangs and doesn't allow you to cancel until it finishes exporting (or fills the whole hard drive). Ability to quickly cancel such export would be really useful.

Please add information about OS/platform and Inkscape version to the bug description, thank you.

To ease further investigation of the reported issue, the bug team would appreciate it if you attach a test case (SVG file) to the bug report, as well as provide details about the PNG image export settings used for the test case (export resolution).

The general issue (cancelling of time-intensive operations) is tracked in this blueprint:
https://blueprints.launchpad.net/inkscape/+spec/intensive-operations-management
and the specific issue with bitmap/PNG export in this earlier bug report:
Bug #1195929 “cannot cancel (huge) export, inkscape hangs while processing”
https://bugs.launchpad.net/inkscape/+bug/1195929

If no further information is provided, I'm proposing to link this report as duplicate to bug #1195929.

Merge it already. As I said there - no information needed is it's insanely easy to duplicate. And it's worrying that it wasn't fixed in any of the previous issues, since it seems to be known for TWO YEARS. :/
