--- Comment #3 from Patrick Silva ---
I'm not sure if the backtrace of the following reproducible crash is the same,
but it's similar at least.
1. open discover
2. search for any of the following apps: volti, screensaver (screen + fire
icon), workrave, xscorch, QasHctl
3. open its description page
Discover freezes and crashes a few seconds later.
Below I"m posting the backtrace after I open description page of workrave.
bug 417800 and bug 418013 seem related/duplicate.
