Comment 4 for bug 917323

This also happened to me. While trying out my bluetooth adapter on Lubuntu for the first time, I received the “blueman-assistant crashed with AttributeError..." message. The error was thrown right after sending a random pairing key to my phone. I was able to pair my phone via serial port after sumitting the crash report, and everything appeared fine. However, blueman kept crashing and I eventually disabled the bluetooth and restarted my computer. Once I booted up again, I tried to pair the phone again. Same as before, blueman threw up the error upon submitting the pairing key. I got the phone paired and tried to browse the phone, but there were no files visible, only folders. Then Lubuntu froze to the point that only my mouse worked. I ended up having to restart my computer again. I tried to view the bug this one is supposedly a duplicate of, but it seems to be gone. Maybe someone can change the status of this one and mark it not a duplicate?
