thunderbird-bin crashed with SIGSEGV in gtk_main_do_event()

Binary package hint: thunderbird

Crash occured while i was typing an email.
I believe i was receiving an email at the same time and that caused the crash.
[this has happened several times earlier , it happens whenever i'm trying to send while something is arriving]

Steps to reproduce:
1: set the "Check for new messages every _ minutes" > to something very small , 1 min or closer.
2: When sending or composing a new mail , if new mail arrives , thunderbird usually freezes. [almost always]

Workaround:
Set the check limit higher , so that there are less chances of this simultaneous event happening.

This error happens with [1] my local yahoo account which uses yahoo's pop server
also , [2] with another yahoo.com account which uses the webmail for pop support.

I havent noticed this with other emails , because the volume of mails in the others is less.

So i'm not sure if this is specific to yahoo or any mail service.
