Thanks for your bug report. Please try to obtain a backtrace http://wiki.ubuntu.com/DebuggingProgramCrash and attach the file to the bug report. This will greatly help us in tracking down your problem.

I was trying to do this but unfortunately failed;
Following the instructions on https://wiki.ubuntu.com/DebuggingProgramCrash and https://wiki.ubuntu.com/DebuggingProgramCrash I added the ddebs-line to apt and installed nautilus-dbgsym.
First I tried running gdb nautilus 2>&1 | tee gdb-nautilius.txt but that did not work. The only output from gdb was

(gdb)

without opening a nautilus window.
I then opened a nautilus window manually, determined the process number and attached gdb to this process. When reproducing my crash however, gdb seemed to crash as well. I used 'force quit' on the nautilus window; gdb did not react to any commands. I then closed the terminal running gdb. Now I cannot open new nautilus windows at all, nor can I kill the window which process number I used above (it seems to be running still, even though the window disappeared).

Some more details about the bug:
This seems to occur when trying to open or copy svg-files created by mathematica via ssh. I believe that only svg-files from mathematica reproduce this crash, but am not sure yet.

If there is more advice on how to debug this I'd be glad to give it a shot.

you need to type continue on the gdb prompt after attaching it to nautilus

Yes that is what I did; it (gdb) stopped reacting upon reproducing my crash (in nautilus) not upon attaching to the process. That's what I was trying to say above, but I case I wasn't clear enough. So again:

I attached gdb to the running nautilus, typed continue in gdb. Nautilus then worked fine. I then proceeded to reproduce my crash by navigating nautilus to the directory in question and copying the .svg file. At this point nautilus crashed (as it usually did for me, that is what the bug is about) but also gdb stopped reacting. No matter what I typed in gdb nothing at all happened.

I hope this makes the problem clear.
Thanks for the help.

Sorry, that seems to have been a different problem. I just tried again, this time it worked.
Backtrace is attached.

the crash there seems to be due to the svg and not similar to what you described, could you attach the svg example?

here's the svg. I can open it in inkscape without problems...

confirmed using the example, that's a librsvg issue

I've similar problems (don't know if it's the same cause):
If I wait some seconds, Nautilus hangs when browsing a folder with an .svg inside, probably while creating the icon preview.
If I disable icon preview it works fine.

I've already posted it in:
