[Bug 981087] [NEW] thunderbird exits if i'm scrolling down the text of an e-mail

[Robin]

Public bug reported:

If I have opened an e-mail in the small window at the bottom of
thunderbird, everything seems okay. But then, if I try to scroll down by
the middle wheel of the mouse, the application closes itself
immediately. Sometimes there is an abstract cursor appering next to the
normal mouse - something like a shadow of an rectangle and the mail is
scrolling down, but only very, very slowly. Everythingis okay if I use
the button on the right site of the window to scroll down the mail.

There is an photo of my desktop in the attachment. It shows the abstract
rectangel which sometimes.

Thank you for your trouble!
