Description Peter C. Trenholme 2020-02-07 04:26:58 UTC

Application: partitionmanager (4.0.0)

Qt Version: 5.13.2
Frameworks Version: 5.66.0
Operating System: Linux 5.4.15-200.fc31.x86_64 x86_64
Distribution: "Fedora release 31 (Thirty One)"

-- Information about the crash:
- What I was doing when the application crashed: Looking at various device and partition descriptions. I'm running a Fedora 31 system using the Plasma desktop on an Intel Atom processor in a Microsoft Surface 3 box, booting from a 2Tb USB-3 drive. I have 2 1Tb micro SD drives, and two Logitech USB device (mouse and keyboard) in an Atolla USB 4-port, powered, USB extender. (The 1Tb Micro SD cards were only ~$20 each on Amazon!) The drives are all recognized as mmcblk devices, and work well. One of the Micro SD cards is formatted as exFAT, the other as NTFS. I suspect, but cannot prove, that the crash occured when I pointed the partition manager at the exFAT (single partition) device. The partition manager screen "blinked out" (e.g., crashed) as soon as I selected one of the two MicroSD chips.

-- Backtrace:
Application: KDE Partition Manager (partitionmanager), signal: Floating point exception
Using host libthread_db library "/lib64/libthread_db.so.1".

I've seen this crash backtrace many times, but somehow was never able to reliably reproduce it. It's appearing at seemingly random times, when doing different things.
