GDB Backtrace of all the processes that were running

SUMMARY
***
Been noticing this one for a while, but whenever I was running gdb on it, it
refused to crash, until today. 
I have a collection of about 100,000 songs, and it is nicely curated. Amarok's
Dynamic playlist is a great feature, as it allows me to finely tune a playlist
suited for the environment. 

Unfortunately is segfaults after running for a while. I have noticed that the
segfaults are more frequent when the filter is set so that it would only match
a small subset of the collection.

***


STEPS TO REPRODUCE
1. Run Amarok on a collection of 100K+ songs
2. Enable Dynamic Playlist
3. Set playlist to search for a specific Genre AND rating of "0" 
4. Let is play for an hour or so.

OBSERVED RESULT
Amarok segfaults after a while

EXPECTED RESULT
Continuous playing until program is stopped from the UI.
