This should be fixed with http://quickgit.kde.org/?p=libbluedevil.git&a=commitdiff&h=c9c115146bcc55133c92087e081b9c1a13ca5e4d which is in libbluedevil 2.0 release. Fedora should have libbluedevil 2.1 in repo, can you please check your libbluedevil version? Also it would be great if you can provide backtrace with debugging symbols. In any case, please note that libbluedevil is now unmaintained.

bluedevil segfault comes if bluetooth subsystem is connected to a2dp (for me) and if i will remove bluetooth adapter (in suspend, for example)
fyi, latest fedora 21 bluedevil in updates is: https://admin.fedoraproject.org/updates/FEDORA-2015-2297/bluedevil-2.1-4.fc21

Hello, David. Your patch helped me to solve my problem. Thanks. I removed USB Bluetooth dongle many times and kded/bluedevil did not crash.

I have pushed the fix, but as I already said, libbluedevil is now unmaintained so there won't be any new releases (which would contain this fix).
