Error: [Exception... "Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch.getCharPref]"  nsresult: "0x8000ffff (NS_ERROR_UNEXPECTED)"  location: "JS frame :: resource:///components/imIncomingServer.js :: <TOP_LEVEL> :: line 175"  data: no]
Source File: resource:///components/imIncomingServer.js
Line: 175

The line in question is 

  get username() this._prefBranch.getCharPref("userName"),

Filing in Im as the comments in the Set that follows the get indicate it is an IM function.

  set username(aUsername) {
    if (!aUsername) {
      // nsMsgAccountManager::GetIncomingServer expects the pref to
      // be named userName but some early test versions with IM had
      // the pref named username.
      return;
    }
    this._prefBranch.setCharPref("userName", aUsername);
  },

Duplicate of bug 747741, but as this has slightly more info I'll dupe it forward.

From bug 758152:
"I would expect this error to only exist on profiles with IM accounts created before the fix for bug 736434 landed, does this match what you observed?"

So recreating my account fixed it at least for me.
Is this acceptable as a workaround or is that bug expected to be fixed?

Thanks for the confirmation.

I'm not sure (I don't really know how many people are affected by this issue), and there were more pressing chat related issues to fix, so I must admit I may not have given this bug all the attention it deserved.

So is it enough to manually rename the pref in pref.js from .username to .userName?

So this only affects users that tried the experimental versions of IM before it got officially exposed in TB15?

It should, yes.

It affects users who created IM accounts on Daily between the 2012-03-12 and the 2012-03-23 builds, and people who created IM accounts on Earlybird between the 2012-03-13 and the 2012-04-02 builds.
