Tracker's file sorting bug

[mr.Noisy]

Hello!

Tracker crashes while sorting files if type-ahead filtering is used. Bug is 100% reproducible on my hrev40649 GCC4/Hybrid.

Here is a backtrace output:

Is the same for me. Tracker crashes while sorting files if type-ahead filtering is used. hrev44240
