The ResourceStore capture function does not call the callback function provided as argument if the server takes a long time (~ 30 s) to respond to the request (the downloaded file is about 400KB).

For other small files, there is no problem.

The problem exists with Gears for Firefox 3.5 (WinXP and OS X 10.5) Gears version: 0.5.33.0;official;opt;osx;firefox

The same function call works with Gears for Safari 4 (OS X 10.5), Internet Explorer 8 (Win XP) and Chrome (WinXP).
