Hi Paul

Thanks for your report.

I am not sure if it is useful as the upstream README.md¹ tells me:
"""
Often people confuses assertions with crashes. Assertions do halt the
program because of a totally unexpected situation. Creating a backtrace
in this situation will only point to the assertion line, which doesn't
help much. In case of an assertion simply post a bug report with the
assertion message.
"""

I believe your liferea failure falls in this category. But we'll see
what upstream says.

Paul

Package: liferea
Version: 1.12~rc1-5
Severity: normal

I got a random crash (SIGABRT) in liferea. If the below gdb backtrace
isn't useful, please close this bug.

$ gdb -batch -n -ex 'set pagination off' -ex bt -ex 'thread apply all bt full'
