Bug Description

Running Maverick-Linux-in-Live-mode.
Opened mozilla-firefox 3.6 and launched About to verify any upgrades available.
Also, opened multiple tabs while reading Mozilla.org documentation.
Downloaded '.tar.gz' archive of browser v8.0.1.
Comparing the '.ini' and '.xml' files to see whats new in the upgraded version, using gedit.
While just trying to paste the upgraded-version-of-browser to replace the one installed by OS by default in Live-Mode.
Also, a window is kept open for accessing a shared-folder on intranet.

Thanks,
K Chandrasekhar Omkar.

Unsetting the need retracing tag, there is no retracer left running on that version of Ubuntu, the crash will need to be manually retraced
