I don't see a problem in seeing a list of weather files/accounts. I don't think it's a sensitive information and it might be helpful sometimes.
This VI service is not used for crashes only, but for all kind of help. E.g.:
a) "Weather plugin stopped working, it doesn't update my stations." -> with this info we can see that user has some old .ini file.
b) "I added protocol X but I don't see it in options." -> with this info we can see that user hasn't created an account.
And it's good point that for creating VI report you need Crash Dumper anyway, so it's better to handle it automatically on files change (or manually from main menu) and not let user save some random/altered text manually.
But I'm still opened for suggestions/arguments.
