Comment 10 for bug 441942

I have three accounts and 2 filter rules.
On my primary account the mail stays in the inbox (On this Computer->Inbox)
On Gmail I have a filter to move it to a gmail folder (On this Computer->Gmail->Inbox)
On my company account I have a filter to move it to a company folder (On this Computer->Company->Inbox)

Only the mail in the On this Computer->Inbox folder will show up in the indicator icon.

It appears that if you apply any filter to a mail it will not appear in the indicator. I did a test using a filter to set the colour of an email if it had a specific subject. I then sent two emails, one with the subject and one without. The inbox then showed 2 unread but the indicator applet only showed 1 new mail.
