Bug 259080

More information: *something* happens after I tell kmail to jump. If I was viewing an HTML message and jump to a folder with HTML turned off, the message will redisplay in text only. And the Folder menu options change (for example, I could not select "Prefer HTML to plain text", it was greyed out)

This includes per-folder shortcuts too. Pressing the combination assigned to a folder has a full flicker and redraw of the message list and message view, but it shows the message it was already showing.

More info: I can jump to folders in the first account (in alphabetical order). I cannot jump to folders in any other account.

    Replace ETM::match() with ETM::modelIndexForCollection()
    
    This fixes the bug that folders of another resource can not
    be used as target for 'Jump to folder' functionality.
