#6 Segmentation fault or failure to render on high sites.

[Jasa Bartelj]

I compiled CutyCapt for amd64 on Ubuntu Linux. libqt4-webkit is at version 4:4.8.1-0ubuntu4.

On some very high websites I get a lot of errors and sometimes a segfault. There's no output graphic, obviously. It seems the project author hasn't been active for over a year, but I'd still like to ask the author or any future forkers to improve error handling and maybe add a maximum height argument.

Here are both examples:

$ time xvfb-run --server-args="-screen 0, 1024x768x24" ./cutycapt-portable-amd64/CutyCapt --url=http://www.worldslongestwebsite.com/ --out=thumb.jpeg --max-wait=48500
