And the backtrace is from plasmashell crash? 1536848 2 wengxt 2015-08-14 08:37:29 +0000 I was using git version bluez-qt, and yes it was from plasmashell since it loaded bluedevil plasmoid and thus loaded bluez-qt. 1538300 3 nowrep 2015-08-20 17:26:22 +0000 Git commit 5771f4256095ac5f295d2b439214d21c5c045ce2 by David Rosca. Committed on 20/08/2015 at 17:25. Pushed by drosca into branch 'master'. Don't forward deviceChanged signal after device was removed This was hitting assert in DevicesModel.
