The center box reads: Thunderbird currently doesn't have any previous conversations stored for this contact.

Pike, do you have any idea about this?

Comment 3

[Axel Hecht [:Pike]]

No idea, maybe Mark?

Also, is there something in the error console that might hint at something?

Comment 4

[Peter Pin-Guang Chen [:petercpg] (MozTW.org)]

Two warning logged: 
1) "Use of Mutation Events is deprecated. Use MutationObserver instead." was logged when switching chat channel/services.

2) "Unhandled IRC message: :concrete.mozilla.org 671 petercpg|iclab-tb petercpg|iclab :is using a Secure Connection" when receiving messages

Also I got some errors reported in bug 786944. Not sure if this is the same case.

The user agent string no longer includes the locale, but this was with the zh-TW version of Thunderbird 15.0.1 on Mac.

Under our tests earlier, Mac and Win32 builds are not affected.

Here is my error messages. I think the reason is error from "Services.prefs.getCharPref" (the first error) that make this._values undefined (the last error).

The reason is that the key font.name.sans-serif.zh-TW is not define (since 

let fontPref = "font.name." + fontGroup + "." + langGroup;
=>  fontPref = "font.name." + "sans-serif" + "." + "zh-TW";
=>  fontPref = "font.name.sans-serif.zh-TW"

A workaround is open about:config 
define font.name.sans-serif.zh-TW = "sans-serif"

I wonder in my about:config I only have the following keys begin with "font.name.sans-serif."
font.name.sans-serif.el = sans-serif
font.name.sans-serif.he = sans-serif
font.name.sans-serif.ja = sans-serif
font.name.sans-serif.ko = sans-serif
font.name.sans-serif.th = sans-serif
font.name.sans-serif.x-cyrillic = sans-serif
font.name.sans-serif.x-unicode = sans-serif
font.name.sans-serif.x-western = sans-serif
font.name.sans-serif.zh-CN = sans-serif
font.name.sans-serif.zh-HK = sans-serif

After regression, the config "font.name.sans-serif.zh-TW" is added by bug 1167072. [2015-05-26]
