I've also installed Gentoo GNU/Linux on the same box with ext3 partitions. The 
partitions which are displayed above are only two of them, other ext3 partitions 
aren't showing up in that directory. And as you can see, there is some invalid 
file also present in that directory which ekiga is not able to figure out. Any 
ideas how to fix this issue.

Since, I've posted it to both freebsd-questions and freebsd-ports, please 
post followups where you think is appropriate place for this.

Thanks
Ashish Shukla
