Bug ID: 471107
Summary: Segfault in feed.cpp:145 when syncing after removing
podcasts remotely
Classification: Applications
Product: kasts
Version: 23.04.2
Platform: Flatpak
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: b...@mogwai.be
Reporter: linus.kardell+kdeb...@gmail.com
Target Milestone: ---
SUMMARY
I recently removed a bunch of podcasts in AntennaPod, which is synced to Kasts
via Nextcloud gPodder, and also removed some podcasts locally in kasts. But
when I did a full sync in Kasts, it crashed, and now it crashes immediately on
launch.
Backtrace:
(gdb) r
