Bug ID: 403839
Summary: Kdeconnectd crash
Product: kdeconnect
Version: unspecified
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: common
Assignee: albertv...@gmail.com
Reporter: g...@rhobard.com
Target Milestone: ---
SUMMARY - Kdeconnect stopped working with my Samsung S6 about three weeks ago.
On the phone I get "This paired device is not reachable..." on the computer I
get a segfault every time I try and launch Kde Connect (via searching for it on
the program launcher and selecting KDE Connect.
Unfortunately, I also get "You cannot report this error because kdeconnectd
does not provide a bug reporting address." Not sure if I should file that as a
separate but report.
STEPS TO REPRODUCE
1. Launch Kde Connect
2. Attempt to pair with phone
OBSERVED RESULT
Kde Connect immediately crashes and throws a segfault.
EXPECTED RESULT
Computer pairs and allows usual activities.
Crash report:
Application: kdeconnectd (kdeconnectd), signal: Segmentation fault
