Summary: Trying to use sftp causes crash in kdeinit5
Product: kio-extras

Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: SFTP
Assignee: plasma-b...@kde.org
Reporter: s.pa...@spiekerbros.com
Target Milestone: ---
SUMMARY
Trying to use sftp (Dolphin, Konqueror, or any other kde-based program) to
access remote locations causes a crash in kdeinit5. Those remote locations that
also support fish are still accessible; it is only sftp which causes the crash
STEPS TO REPRODUCE
1. try to access a remote location using sftp
OBSERVED RESULT
kdeinit5 crashes and dolphin (or other program) shows "unknown error". Keeping
the Dolphin window open will result in repeated crashes.
EXPECTED RESULT
dolphin shows the contents of the remote folder
