// trying to send it one more time
I don't think it is a serious problem, however it may help creating malicious e-mails or webpages that may crash any proggie that uses IE to render html content.
You may test it by visiting the following page http://www.sztolnia.pl/hack/googIE/googIE.html It should crash IE [Google Toolbar must be installed] [an exception is raised in oleaut32.dll]
Tested on IE 5.5, 6.0/Google Toolbar 1.1.60
