I was searching for images on Google images and when I right click on an
image and paste it into librewriter, the cpu usage goes to 100% and I
have to force quit librewriter. This happens on all versions of
librewriter from 3.x to 4.2 on Ubuntu (10.04 to 13.1). I've also seen it
on Windows, but have not tested it as thoroughly. This does not happen
in librecalc, impress, or draw. The drawback in writer is you may lose
all your work once you paste an image. If you paste special -> bitmap it
pastes the image.

Can this crash be prevented or treated the same as the other libreoffice
applications? Thank you!

It looks like a bug is already filed:
I've just signed up for an account on the bug tracker, so will add more info to that report when I can get in. In the meantime...

I can confirm this in LibreOffice Writer, copying from Mozilla SeaMonkey 2.23, on Windows Vista. Copying static images from a couple of other websites was no problem, so it seems to be partly to do with the way Google Images search works.

Copying from other websites into Writer, I first see a placeholder which is then replaced with the image. The time it takes to show the image increased with image size, so looks like LibreOffice gets a link to the image, then downloads it itself. However, the URL copied from Google isn't a link to an image on a web server (it begins "data:" rather than "http:") - I guess the image data is obtained via JavaScript or JSON or something in the web browser, but that link won't then work for another application. Not good that it crashes LibreOffice Writer though!

I'm not sure about Linux, but on Windows a "copy" operation can put data on the clipboard in several formats, and the "paste" operation can then use any one of those (usually a default, with "paste special" giving the user a choice). Copying an image from the web browser appears to place data on the clipboard in HTML and bitmap formats, where the HTML includes a link to the image as well as alt text etc.

It looks like Writer uses the HTML by default and attempts to download the image data itself, while Draw and Impress use the image data from the clipboard. Presumably Writer does something useful with the other HTML attributes which Draw and Impress don't, but looks like it needs to handle "data:" links more gracefully.

As you've found, a workaround is to use Paste Special > Bitmap (this tells writer to use the bitmap data from the clipboard rather than the HTML) - but that doesn't exactly help when you automatically hit default "Paste" and Writer hangs!
