Bug 89341 – [Chromium] iccjpeg doesn't work with browser_tests

• Status: RESOLVED
• Resolution: WONTFIX
• Component: Platform

[Hajime Morrita]

hbono@ kindly told me that  some browser_tests runs renderer in a separate thread
and that breaks this assumption.

Landed a bandaid fix: http://trac.webkit.org/changeset/120582
A straightforward fix might be calling this function somehow from a WebKit initialization routine.

Greetings,

To look at this stacktrace, it seems extension code decodes images on a FILE thread with WebKit: <http://code.google.com/searchframe#OAMlx_jo-ck/src/chrome/browser/extensions/image_loading_tracker.cc&exact_package=chromium&l=103>.

The browser process is not allowed to decode images.  That code will likely need to be changed.  Would you be willing to file a crbug.com about it and CC me?
