Bug Description

After I successfully log into Gmail (http://mail.google.com) via Firefox and the page has finished loading, I begin receiving the following error message continuously in the Javascript Console:

Error: malformed Unicode character escape sequence
Source File: javascript:yj_api0_DoFSCommand('msg','%5B%22%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%22%2C%22%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%22%2C%5B%22%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%5Cu0NaN%22%5D%5D')
Line: 1, Column: 26
Source Code:
yj_api0_DoFSCommand('msg','["\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN","\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN",["\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN\u0NaN"]]')

This does not seem to effect the functionality of Gmail itself but, as stated prior, it continually adds to the console until I close the tab (making web development difficult).

I have used Chromium and did not receive the error. I have used FF on a Windows machine and did not receive the error. This leads me to believe that it is the specific combination of Gmail + FF + Ubuntu.

I was just searching for this error and found your report. I've just being experimenting with turning off one add-on at a time and the bug seems to be from (Gnash) Shockwave Flash.
I too am using Gmail + FF + Ubuntu. I use many other add-ons but they don't seem to affect this bug.
If I disable Gnash's Shockwave Flash, the console errors stop. This is easiest to see by clearing the console each time, you probably know this doing development. If I re-enable Gnash and refresh GMail's page, the errors recur. Thanks to Firefox's way of handling add-ons, I didn't even need to quit FF and reload.
I'm using Gnash's "Shockwave Flash 10.1 r999. Gnash 0.8.10dev". Googling, I haven't find much about Gnash's latest version other than http://www.gnu.org/software/gnash/download.html
Now I'm off to dig for info on this add-on's bug. I don't fancy debugging Gnash's source code, so disabling it temporarily is a kind of workaround, much as I like Gnash because it's not Flash.

Thanks, Kevin. I wish I didn't have to use a workaround but turning off the add-on worked.

I hope you find the solution to this because I don't know where I would even begin to solve it.
