/debug/mozilla/intl/strres/src/nsStringBundle.cpp, line 223

Comment #1 [reply] Gavin Sharp  2008-02-20 19:41:43 PST

The extension code defines:
performancingUI.getLocaleString(strName, formattingValues)
and passes (strName, formattingValues) directly to
<stringbundle>.getFormattedString() if formattingValues is defined, which calls
nsIStringBundleService::formatStringFromName.

The extension is full of calls to performancingUI.getLocaleString that pass in
an empty array as the "formattingValues" parameter. Since it isn't undefined,
it calls getFormattedString which calls formatStringFromName which produces the
assertion. The extension code should stop doing that.
