I think there is really two parts to this bug.

1. We should validate the formatting tags when a user enters a song manually:
    a) For 2.0 series think we should display a message box saying that the formatting tags are invalid.
    b) For trunk series, I was thinking it would be nice if we could highlight the actual issues. Either with a message box  for example "x opening tag found, but no closing tag" or by actually changing the background colour of the tag to red or something.

2. For songs that are being imported or songs that are already in the
database we should either remove the tag, or close it just before the
next closing tag or split.

Bug description:
  There is another bug similar to this, bug #885874, but it does not
  seem to have fixed the issue below. Note that there is a mismatched
  "{/g}" tag which causes this error.

  --- Details of the Exception. ---

  Hi,
  I just found one bug. I just changed one Bridge to:

  Shine Your light and {g}Strahle hell und{/g}
  Let the whole world see {g}lass die Welt es sehn.{/g}
  We're singing {g}Wir singen{/g}
  For the glory Of the risen King{/g} {g}dir zur Ehre, auferstandner Herr.{/g}
  Jesus

  And got this error:
