Summary: plasmashell crashes when searching in kickoff
Product: frameworks-baloo
Version: 5.29.0
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: pinak.ah...@gmail.com
Reporter: o...@geek.co.il
Target Milestone: ---
Ever since upgrading to Neon developer edition (5.8.95), plasmashell crashes
whenever opening the application launcher and searching. Just browsing the
application launcher works fine.
When I reproduce the problem under GDB, I get this error and this stack trace:
Thread 13 "GlobalQueue[02]" received signal SIGBUS, Bus error.

I have a similar issue in krunner, which I haven't reprod under GDB yet, but I
believe it has the same cause.
After running `balooctl disable`, the crash does not happen anymore, neither in
Kickoff nor in KRunner.
I'm currently running the Neon debian package version
5.29.0+p16.04+git20170104.0753-0
