This command was intended to copy the MBR, partition table, and first partition of the USB flash drive with a RHEL 7 installation. /dev/sdd1 was the only partition and it was ~13 GiB in size. - Unusual behavior I noticed: Baloo crashed and KDE gave me a window saying so. - Custom settings of the application: What happened, step-by-step: 1. Inserted the SanDisk Ultra 128 GB drive into a USB 3.0 port 2. Opened Konsole and typed "cat /proc/partitions" to determine what the drive assignment was. The USB drive was assigned "/dev/sdd" with a single partition. 3. Typed "sudo fdisk -l /dev/sdd" to obtain the 'End' column of the first partition. I used the 'End' column, plus 1 block to give 27265024. With a block size of 512 bytes, I continued to step 4. 4. Typed "sudo dd if=/dev/sdd of=RHEL7.ddimg bs=512 count=272650234" to obtain the MBR, partition table, and first partition of the USB drive. 5. Baloo crashes. Can't stop the fever. Baloo just infects and eats your face off. The crash can be reproduced every time. -- Backtrace: Application: Baloo File Indexing Daemon (baloo_file), signal: Aborted Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

I'll investigate, but it will take some time. Please be patient and for the time being do this: Open a console <optional> in a second console $ balooctl monitor </optional> $ balooctl suspend (Do your dd stuff) $ balooctl resume <optional> baloo should list the files it is indexing in console #2 Please report what happened </optional> If that doesn't help try the balooctl start/stop pair instead of suspend/resume. Ensure baloo_file and baloo_file_extractor are not running after balooctl stop. 1745461 2 dhaumann 2018-04-14 01:57:43 +0000 @Michael: This bug was reported since many years many times.
