Reproduced this with Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.7)
Gecko/20040626 Firefox/0.9.1
So this is not new.

Firefox certainly shouldn't crash under these circumstances, but I'm not
entirely sure how it should react either. How does it know what to look for when
the stylesheet location is ambiguous (i.e. a directory rather than a full path)?

I wouldn't recommend bandaiding this, since it's an extremely unlikely to be
discovered crash. 

Just a thought... is this bug present on the trunk? If not, we should WONTFIX
this bug (IMO) and wait until the post-1.0 Branch/Trunk merge to automatically
fix it. Can someone please add the talkback IDs to the status whiteboard? Thanks.

Attachment: CSS for minimal testcase

Attachment: HTML for minimal testcase

Minimal testcase. Please notice that if the same CSS file is the primary
stylesheet, there is no crash.

I don't think this has anything to do with the stylesheet location, but rather
with its content.
Please seem my testcase, in which the stylesheet location is specified as an
absolute URL.

You are correct, my mistake. The problem also occurs when doing this locally
with your minimal testcase.

This also crashes the suite: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US;
rv:1.7.2) Gecko/20040803

Looks like a dupe of Bug 231776

Yes, this is a duplicate (darn! I thought I finally found a good bug!)
More specifically, see bug 229263 (which was closed as a dupe of 231776).
