From Bugzilla Helper:
User-Agent: Mozilla/4.7 [en] (X11; I; Linux 2.2.10 i686)
BuildID:    M15 and latest nightlies, e.g. 2000042113 and 2000042309

Opening the above URL in composer crashes mozilla. This seems to be caused by
the <SELECT> element contained in that document.

Reproducible: Always
Steps to Reproduce:
1. go to http://www.mozart-oz.org/
2. select "Edit Page" from the File menu

Actual Results: composer window opens, then mozilla crashes with segv

Here's a piece of HTML code that triggers the bug:
If you replace the URL above with the file:/... URL for a local file
containing this, the result is the same.

The backtrace begins with
#0  0x0 in ?? ()
followed by "...in NSGetModule () from /components/libraptorhtml.so"
several times.

I submitted several talkback reports while tracking this down.

I think it's a little worse than that.. can you at all open a file from local
disk with filepicker? see bug 36842

Yes, sure it's worse... ;-)
Well, I had seen bug 36842 before, but it seems to be something different:
- the stack traces do not show any similarities
- this bug already occurs in M15, whereas bug 36842 seems to quite new
For example, I can successfully open my homepage with the file picker with M15.
So these are completely different issues.

By the way, thanks for your tips about gdb. As you can see, it works... :)
I agree that the newest nightlies are really bad in terms of usability.
I'll have a look at bug 36842 and confirm it if I can reproduce something.

i've had three different stacktraces on it, terminatig with SIGSEGV or SIGILL
so the only certain thing is that it crashes. btw - first thing to do when
starting composer: uncheck sidebar.

the above server is down or something, I can't access the file. I'll try again 
later to see if I can get to the site

I see this crash on a Mac build from today too.
Reassign to sfraser since he might already have a bug for this (but maybe not 
since this is a crashing bug so it may be different).

Stack trace is the same. Marking duplicate.
