[Bug 1209095] [NEW] Thunderbird hogs CPU while waiting for master password

[Benkinooby]

Public bug reported:

1) Ubuntu 12.10

2) Package: thunderbird
Architecture: i386
Version: 17.0.7+build1-0ubuntu0.12.10.1

3) expected behaviour:
* I start Thunderbird
* Thunderbird idles at less than 1% CPU usage (I don't let it fetch mails at start up)
* I click "Get Mail" and Thunderbird asks me to enter the master password.
* While Thunderbird is waiting for me to enter the master password, it should use the same amount of ressources as it does when ideling.
* After entering the master password, Thunderbrid fetches the mail and then idles at less than 1% CPU usage

4) current behaviour:
* I start Thunderbird
* Thunderbird idles at less than 1% CPU usage (I don't let it fetch mails at start up)
* I click "Get Mail" and Thunderbird asks me to enter the master password.
* While Thunderbird is waiting for me to enter the master password, Thunderbird hogs up to 40% of my CPU until the master password is entered.
* After entering the master password, Thunderbrid fetches the mail and then idles at less than 1% CPU usage

5) additional info:
I use three POP and one IMAP account.
