-- Information about the crash:
- What I was doing when the application crashed:
I was surfing the web when Apper twice notified about:
"An unknown error happened"

- Unusual behavior I noticed:
I could not save nothing to /tmp. I tried opening a pdf with a browser and it said it could not save to /tmp/file.pdf, but it successfully saved to home

-- Backtrace:
