Comment 1 Luis Silva 2015-10-11 10:50:26 UTC
This crash disappears after running:
balooctl disable
balooctl enable

So resetting the database solves the issue.
Some extra info, previously, before reinstalling this machine, I was compiling baloo from master.

New crash information added by DrKonqi

baloo_file (5.15.0) using Qt 5.4.2

- What I was doing when the application crashed:
Fresh install of Kubuntu 15.10. 
Homedir preserved, but removed all .-folders

Crash happened on first login.

- Custom settings of the application:
/home is on nfs4.1+kerberos, mounted by autofs:

freeman:/home/jan on /home/jan type nfs4 (rw,noatime,vers=4.1,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=krb5p,clientaddr=192.168.123.2,local_lock=none,addr=192.168.123.1)

Eh, env is null. The env failed to init.
