Well a walk around would be releasing a new version with the bug fix. I heard this some times happens with toasts, if it does for you please say so. The next release will be Messenger Plus! Live, and entire re-code of Messenger Plus!. However, if the problem still occurs please report it to us.
Also try and sumbit your buf report here, it may help with your problem. Otherwise I don't think you can do anything else. Sorry
