One small important detail is missing :-) This dump indicates an assertion (first thread has g_assertion_message in it). There was a CLI output that probably explains the dump. This would be really helpful

[paulgevers]

@lwindolf: unfortunately the reporter doesn't run liferea from the command line, so the output was never visible. I suggest to close this bug if it is lacking the required info.
