Comment 1 Martin 2012-06-07 13:29:17 UTC 
Actual results:
kded4 crash after media insert
Comment 2 Ludek Smid 2012-06-22 14:43:42 UTC 
Could you provide status update? RHEL 7.0 Alpha 2 RC compose starts July 6.
Comment 3 Than Ngo 2012-06-25 08:30:21 UTC 
it's a bug in solid backend which is part of kdelibs. It should be fixed in kdelibs-4.8.3-4.el7.
