Bug ID: 402542
Summary: Failed copy from mtp with large number of files and
large amount of data
Product: kio-extras
Version: 18.12.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: MTP
Assignee: elvis.angelac...@kde.org
Reporter: cmrnt...@gmail.com
Target Milestone: ---
Started dolphin, used mtp to enter folders on andoid cell phone, selected 602
files comprising 16.3 GB of data, mostly images, copied and then pasted into an
empty folder on desktop. Due to the amount of data, the job took a long time.
System became slow to respond so I decided to be patient and let the job
finsish. While waiting, the screensaver started. Attempt to log in failed
despite entering the correct password and screensaver crashed leaving only a
mouse pointer. Crtl-Alt-F1 to log in as root, top showed high cpu usage 12+,
but no job registered more than 20% of cpu. Eventually even the root terminal
became unresponsive leaving power button reboot as the only option.
STEPS TO REPRODUCE
1. Plug in android phone with USB-C connector
2. Start dolphin
3. Click phone icon in panel to left for mtp access to its files
4. Navigate to mtp:/V30S/Internal storage/DCIM/Camera/
5. Select a large number of files
6. Copy files
7. Paste files into an empty folder on the desktop
OBSERVED RESULT
System slows progressively and eventually is unresponsive requiring a hard
restart.
EXPECTED RESULT
Files copied successively to destination folder
