Plugin bug barrier....

I am getting occassional stacktraces (included below). The dialog indicates these are not directly postable because they are a plugin related problem. I don't run any plugins except those that come with IDEA, so perhaps JetBrains needs another indicator (ie. vendor). Do you guys really not want bugs from your own plugins?
