Gloobus crashes when trying to go to next file using arrows

[kcpr]

Gloobus Preview version 0.4.5, installed from ppa.
Using Ubuntu 11.10 32-bit.

Example:

kcpr@michal-ubuntu:~$ gloobus-preview /home/kcpr/Pulpit/szermierka/5.pdf

Sometimes it doesn't work at all - instantly after pressing arrow key Gloobus crashes:

kcpr@michal-ubuntu:~$ gloobus-preview /home/kcpr/Pulpit/Nicole/100_7804.JPG

I've never noticed this bug while using previous version.

Same bug on Ubuntu 12.04.
