Application: baloo_file (5.6.2) Qt Version: 5.4.1 Operating System: Linux 3.19.0-26-generic x86_64 Distribution: Ubuntu 15.04 -- Information about the crash: - What I was doing when the application crashed: I created a new FAT32 partition on a USB stick using gnome-disk-utility 3.14.0 (UDisks 2.1.5 (built against 2.1.4)). Baloo suddenly crashed, presumably after the partition was created trying to index it. The plasma desktop disappeared for a while and then came back. - Custom settings of the application: Baloo still had the default settings, i.e. no directories to skip listed. -- Backtrace: Application: Baloo File (baloo_file), signal: Aborted Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Created attachment 94403 [details] backtrace of plasma crash which happened at the same time Apparently plasma crashed at the same time as Baloo. I'm attaching the corresponding backtrace.
Created attachment 94404 [details] Another crash after re-attempting partitioning Another Plasma crash after re-attempting partitioning. Baloo search was disabled beforehand this time.
"Workaround" for the partitioning: I've had several more plasma crashes since last time, whether using the KDE partition manager or the gnome-disks. gnome-disks tended to always crash while trying to create the second ext4 encrypted partition on the flash drive, after having created a first FAT32 partition. The error message seemed to always be: "Error wiping newly created partition /dev/sdb2: Command-line `wipefs -a "/dev/sdb2"' exited with non-zero exit status 1: wipefs: error: /dev/sdb2: probing initialization failed: No such file or directory (udisks-error-quark, 0)" As a workaround, I installed openbox to run gnome-disks from there, but the crash still happened. Based on this https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=767457 , I ran the failed wipefs command manually and then successfully created the encrypted partition from within gnome-disks. Anyway, while it seems baloo/plasma were not behind the partitioning failure, they still seem to have crashed because of it. [although despite running openbox, some KDE stuff was running: $ ps ax | grep kde 63 ? S 0:00 [kdevtmpfs] 10242 ? Sl 0:00 /usr/bin/kded5 10246 ? Ss 0:00 kdeinit5: Running... 10247 ?
