Application: bluedevil-monolithic (2.1.1)
KDE Platform Version: 4.14.8 (Compiled from sources)
Qt Version: 4.8.6
Operating System: Linux 4.1.12-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed: removed a bluetooth USB dongle

- Unusual behavior I noticed: I use this dongle to connect my phone to the PC. It usually fails to connect when I resume the PC from suspend. Removing the dongle and re-inserting it again solves the issue until the next suspend.

The crash can be reproduced every time.

-- Backtrace:
Application: Bluetooth (bluedevil-monolithic), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
